Answers
Answer:
Hi! To find x (the missing angles of the triangles), remember that the angles in a triangle add up to 180 degrees. This means that for each triangle, you can add the two angles given, then subtract that number from 180 to find x. I'll use Triangle 1 as an example:
81 + 84 = 165
180 - 165 = 15
So for Triangle 1, x is equal to 15.
To classify each triangle by angles, remember that an acute triangle has three angles that each measure less than 90 degrees, a right triangle is a triangle with one 90 degree angle, and an obtuse triangle is a triangle with one angle that is greater than 90 degrees. To classify each triangle by sides, remember that scalene triangles have three sides of unequal length, isosceles triangles have two sides of equal length, and equilateral triangles have three sides of equal length.
Keeping all this in mind, here are your answers:
Triangle 1 - 15 acute scalene
Triangle 2 - 120 obtuse scalene
Triangle 3 - 41 right scalene
Triangle 4 - 104 obtuse isosceles
Triangle 5 - 25 right scalene
Triangle 6 - 64 acute scalene
Triangle 7 - 72 acute scalene
Triangle 8 - 32 obtuse scalene
Triangle 9 - 40 right scalene
I hope this helps you! Have a great day. - Mani :)

Check whether the given value of x is a solution to the equation. Justify your answer. 1/3(x+4)=20. x=56.
Answers
Answer:
True, it is a solution
Step-by-step explanation:
First, let’s distribute 1/3 to x and 4
When we do this, we get:
1/3x+4/3=20
Now, we can solve the equation!
Subtract 4/3 from each side of the equation to isolate the x
We now have 1/3x=18 2/3
Now we divide 1/3 on each side to isolate the x (this is the same as multiplying by 3/1 on each side)
This gets us to x=56
So it is true

QUESTION 1: TRANSPORT Mr Dlamini transport people between Butterworth and East London using a bus which has a capacity of 100 people. The transport charge starts with a minimum charge of R8 and thereafter it was increased by R2 for each kilometre. On a particular day the bus was full with passengers from Butterworth. In each and every kilometre there was a passenger getting off while no new passenger entered in the bus. Mr Dlamini was calculating total money in his hand after each passenger was getting out. The total amount he has after each stop can be written as a series as follows: S. = 8 + 10 + 12 + 14 +... Use the series to calculate the following questions 1.1 (1) Term 2 (T2) = Sum of first two terms (S2) (2) (ii) Express T2 in terms of S, and S2. (1)
Answers
From the series, it can be deduced that the sum of the first two terms will be 18.
How to calculate the seriesFrom the information given, it was stated that the transport charge starts with a minimum charge of R8 and thereafter it was increased by R2 for each kilometre.
The series is also given as S. = 8 + 10 + 12 + 14 +... Therefore, the sum of the first two terms will be:
= 8 + 10
= 18
Expressing T2 in terms of S, and S2 will be T2 = S + S2.

Answers
Answer:
Equation: y = 2x + 25
Step-by-step explanation:
Here x determines the number of year. For the first year,we will see ( 2 * 1 ) = $2 increase. In the second year, ( 2 * 2 ) =$4 increase and like this goes on, whereas the $25 being constant. "y" determines the total cost for each year.
Therefore the equation can be made: y = 2x + 25

Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are in proportion, that is
[tex]\frac{MO}{PR}[/tex] = [tex]\frac{MN}{PQ}[/tex] ( substitute values )
[tex]\frac{4+x}{5}[/tex] = [tex]\frac{x-2}{2}[/tex] ( cross- multiply )
5(x - 2) = 2(4 + x) ← distribute parenthesis on both sides
5x - 10 = 8 + 2x ( subtract 2x from both sides )
3x - 10 = 8 ( add 10 to both sides )
3x = 18 ( divide both sides by 3 )
x = 6

Question #12: There are 15 pieces of fruit in a bowl. 6 of them are pears. What
percentage of the total fruit in the bowl are pears?
Answers
since our denominator in 6/15 is 15, we could adjust the fraction to make the denominator 100. To do that, we divide 100 by the denominator:
100 ÷ 15 = 6.6666666666667
Once we have that, we can multiple both the numerator and denominator by this multiple:
6 x 6.6666666666667/15 x 6.6666666666667
= 40/100
Now we can see that our fraction is 40/100, which means that 6/15 as a percentage is 40%.
We can also work this out in a simpler way by first converting the fraction 6/15 to a decimal. To do that, we simply divide the numerator by the denominator:
6/15 = 0.4
Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:
0.4 x 100 = 40%
And there you have it! Two different ways to convert 6/15 to a percentage. Both are pretty straightforward and easy to do, but I personally prefer the convert to decimal method as it takes less steps.
Answer:
40%
Step-by-step explanation:
6/15 = 0.4 = 40%
All these mean the same them, but what we are looking for is a percentage, which is 40%.

A wire 90 cm long is cut into two pieces. One
piece is twice as long as the other piece. How
long is the shorter piece of wire?
Answers
Answer:
30 cm
Step-by-step explanation:
30+60=90
30×2=60 so 30cm is the answer.
Step-by-step explanation:
If one price is 2 times the other one, that means it's equal to 2 of those parts. Let's decide our total wire by three to account for the larger part.
[tex]90 \div 3 = 30[/tex]
Now we know the shorter piece is 30 cm. To find the longer piece, multiply the shorter piece by 2.
[tex]30 \times 2 = 60[/tex]
Recap:
Shorter Piece: 30 cm
Longer Piece: 60 cm

Which is a factor of x2 – 9x 14? x – 9 x – 2 x 5 x 7.
Answers
Answer:
Step-by-step explanation:
The 2 factors of x^2 - 9x + 14 are (x - 7) and (x - 2) because -7 + -2 = -9 and -7 x -2 = 14.
The factors of the quadratic expression x² – 9x + 14 is (x - 7)(x - 2) option (B) (x - 2) is correct.
What is a quadratic function?Any function of the form [tex]\rm f(x) =ax^2+bx+c[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic function.
It is given that:
The quadratic expression is:
= x² – 9x + 14
Using factor method:
= x² – 7x - 2x + 14
= x(x - 7) - 2(x - 7)
= (x - 7)(x - 2)
The factors of the quadratic expression x² – 9x + 14 is (x - 7)(x - 2)
Thus, the factors of the quadratic expression x² – 9x + 14 is (x - 7)(x - 2) option (B) (x - 2) is correct.

In Figure 1 :- In figure 1 , we have given everything we don't need to determine anything in figure 1 In Figure 2 :- Here, we have to determine the measure of sides ,braces and angles with least number of known measures,Let's start ,
From the figure, we can assume the beam forms as AD, BC, EF , GH and so on.
Therefore,
[tex]\sf{ ABCD , AEFD, AGHD.. so \:on similar\: to \:each \:other }[/tex]
So,
