Step-by-step explanation:
A linear pair of angles is formed when two lines intersect.
Two angles are linear if they are adjacent angles formed by two intersecting lines.
Since the measure of a straight angle is 180°, a linear pair of angles must add up to 180°.
1. Two angles that add up to 180° are called supplementary.
2. The image shows a linear pair of angles. On the left side, the angle measures 2x, on the right side, the angle measures x+30. Since the sum is 180°:
2x + x + 30 = 180
Simplifying:
3x + 30 = 180
Subtracting 30:
3x = 180 - 30 = 150
Dividing by 3=
x = 150 / 3 = 50
x = 50°
3. The angle on the left is 2x = 100°
Angle measure on the left = 100°
4. The angle on the right is x+30 = 80°
Angle measure on the right = 80°

Answer:
Option 2: 5.34 is the correct answer.
Step-by-step explanation:
As it can be seen that the given triangle is a right-angled triangle.
Here
Base = 12
Perpendicular = x
θ = 24°
We can use trigonometric ratios to find the value of x. We have to choose a trigonometric ratio which involves base and perpendicular as we only know these two and the angle in the triangle
So,
[tex]tan 24 = \frac{perpendicular}{base}\\0.4452 = \frac{x}{12}\\x = 0.4452*12\\x = 5.3424[/tex]
Rounding off to nearest hundredth
x = 5.34
Hence,
Option 2: 5.34 is the correct answer.

A shop sells 20 different flavors of ice cream, in how many ways can a customer choose4 ice cream cones (one dip of ice cream per cone, please) if they:_________(a) are all of different flavors.(b) are not necessarily of different flavors.(c) contain only 2 or 3 flavors.(d) contain 3 different flavors.
Answers
Answer:
a.4845ways.
b. 14535ways.
c. 3990ways
d. 1140ways
Step-by-step explanation:
Given data:
No of flavors available to customers = 20.
Solution:
This is permutation and combinations problem,
(a) how many ways can the customers choose 4 different ice creams if they are all of different flavors.
20C4
= n!/(n-k)!)k!
= 20!/(20-4)!)4!
= 20!/(16)!)4!
= 4845ways.
b) are not necessarily of different flavors
Let’s say any two same flavors can be chosen.
20C4 * 3!/2!
= 4845 * 3
= 14535ways.
c) contain only 2 or 3 flavors.
= 20C3 * 3!/2!
= 1140 * 3
= 3420
20C2 * 3
= 190 * 3
= 570.
No of 2 or 3 different flavors
= 3420 + 570
= 3990ways.
d) contain 3 different flavors.
20C3
= n!/(n-k)!)k!
= 20!/(20-3)!)3!
= 1140ways.

Let f(x) = 5x + 4 and g(x) = x2 - 4. Find the following.
(gof)(-2)
Answers
Answer:
(g ￮ f)(-2) = 32
Step-by-step explanation:
Given
[tex]f(x)=5x+4[/tex]
[tex]g\left(x\right)=x^2-4[/tex]
We have to evaluate (g ￮ f)(-2), so first we will evaluate f(-2) then use this value to evaluate g(x).
Finding f(-2)
[tex]f(x)=5x+4[/tex]
[tex]f(-2) = 5(-2)+4[/tex]
[tex]= -10 + 4[/tex]
[tex]= -6[/tex]
Then
[tex]g\left(-6\right)=\left(-6\right)^2-4[/tex]
[tex]=36-4[/tex]
[tex]= 32[/tex]
Therefore,
(g ￮ f)(-2) = 32

Answer:
2(x+4)
Step-by-step explanation:
To factor you have to divide both terms by the greatest common factor, which in this case is 2. Using distribution you can check your answer.
Answer: 2(x + 4)
Explanation: If you're asked to factor a polynomial,
the first thing you want to look for is the greatest common factor
for the terms that are involved.
The greatest common factor of 2x and 8 is 2.
So a 2 can factor out.
Inside the parenthses, we have each term divided by
the 2 that factored out of the polynomial.
So we have 2(x + 4).

Solve the inequality 3(x+1)<18
Answers
Answer:
3(x+1)<18
3x+3<18
3x<15
x<5
Step-by-ste3(x+1)<1p explanation:
First we have to apply the Distribution Property to the left side of the inequality.
3(x + 1) = 3(x) + 3(1)
3x + 3 < 18
Now we get the term 3x alone by subtracting 3 on both sides.
3x + 3 - 3 < 18 - 3
3x < 18
Now all we have to do is get x alone to find out what would be the values of x is. And since the number we are dividing by isn’t a negative, we don’t have to flip the sign.
3x/3 < 18/3
x < 6

There were 5 women, 4 men, 6 girls and 7 boys at a birthday party.
How many ways can 1 woman and 1 man be chosen to take coats as
people enter?
Answers
Answer: 20 ways
Step-by-step explanation:
Given: There were 5 women, 4 men, 6 girls and 7 boys at a birthday party.
i.e. Number of women = 5
Number of men = 4
According to the fundamental counting principle , we have
(Number of women ) x (Number of men)
= 5 x 4
= 20
Hence, 1 woman and 1 man can be chosen in 20 ways to take coats.
