(ASAP!!)Two base angles of an isosceles triangle measure (3x + 2) and (5x - 30) degrees. How many degrees are in the third angle of the triangle? Be sure to use the correct place value.
Answers
Answer:
Measure of third angle = 80°
Step-by-step explanation:
Property of an isosceles triangle,
Opposite angles of the equal sides of an isosceles triangle are equal in measure.
Since, base angles of an isosceles triangle are equal,
(3x + 2) = (5x - 30)
5x - 3x = 2 + 30
2x = 32
x = 16
Now measure of the base angles will be = (3×16) + 2 = 50°
Let the measure of third angle = y°
Since, sum of interior angles of a triangle = 180°
50° + 50° + y° = 180°
y + 100 = 180
y = 80°
Therefore, measure of third angle is 80°.

A bag contains 3 red balls, 8 blue balls and 11 white balls. What is the probability of drawing two balls after replacing the first ball; first is red and then a white ball? Round to the nearest tenth and include a percent sign
Answers
Answer:
0.1Step-by-step explanation:
Probability = expected outcome/total outcome
If a bag contains 3 red balls, 8 blue balls and 11 white balls, then the total outcome will be;
Total outcome = 3 + 8 + 11 = 22 balls
Since we are drawing two balls with replacement;
Probability of drawing red ball = number of red/total outcome = 3/22
Probability of drawing white ball = number of while/total outcome = 11/22 = 1/2
Probability of drawing red first and then white = 3/22 * 1/2
Probability of drawing red first and then white = 3/44
To the nearest tenth, 3/44= 0.1
In percent = 6.8%
the figure is used as part of a visual description of an algebraic statement. Which of the following can be that algebraic statement?
A.a^2 +b^2=c^2
B.1/2 (a+b) =c
C.a•b=c
D.a^2•b^2=c^2
Answers
Answer: A.
Step-by-step explanation:
The correct algebraic statement is [tex]a^{2} +b^{2} =c^{2}[/tex].
Pythagoras Theorem:It states that "the sum of the areas of the two squares on the legs (a and b) equals the area of the square on the hypotenuse (c)" i.e.
[tex]a^{2} +b^{2} =c^{2}[/tex]
According to the given question
By Pythagoras theorem we can say that the algebraic statement A i.e.[tex]a^{2} +b^{2} =c^{2}[/tex] is the correct one for the description of given figure.
Hence, option A i.e. [tex]a^{2} +b^{2} =c^{2}[/tex] is the correct option.

The next number in the sequence 3, 7, 12, 18, 25, 33, 42
Answers
Answer:
You add 4 and add 5 and then add 6 you add 1 more extra every time!
Step-by-step explanation:
The next number in the sequence is 52. The extended sequence becomes: 3, 7, 12, 18, 25, 33, 42, 52.
To find the pattern in the sequence and determine the next number, let's look at the differences between consecutive terms:
7 - 3 = 4
12 - 7 = 5
18 - 12 = 6
25 - 18 = 7
33 - 25 = 8
42 - 33 = 9
The differences between consecutive terms are increasing by 1: 4, 5, 6, 7, 8, 9. Now, to find the next number in the sequence, we continue the pattern by adding the next number in the sequence of differences: The last difference was 9, so the next difference will be 9 + 1 = 10.
Now, add this difference to the last number in the given sequence:
42 + 10 = 52.

Determine whether each option below would result in any part of the picnic table being shaded by the umbrella at mid-
day. Explain how you know.
• Option A: Rotate the picnic table 90° clockwise about the point (5, 0).
Option B: Move the umbrella to a location 4 feet to the left and 1 foot down.
• Option C: Move the umbrella to a location 3 feet down and 2 feet to the left.
Enter your answers and explanations in the space provided
Answers
Answer:
Option CStep-by-step explanation:
Refer to attached picture
At midday the shaded area is going to be under the umbrella only, therefore the option moving the table under the umbrella will be the answer.
So the options:
Option A: Rotate the picnic table 90° clockwise about the point (5, 0)
No. The table has dimensions of 4x3, after this rotation the distance between the umbrella and the table will be zero but the table won't go under the umbrella.Option B: Move the umbrella to a location 4 feet to the left and 1 foot down.
No. The movement will bring the umbrella down by one feet and no intersections.Option C: Move the umbrella to a location 3 feet down and 2 feet to the left.
Yes. By moving the umbrella down by 3 feet and to the left by 2 feet, it will cover some part of the table. The lowest point of the umbrella will have the coordinate of (5, 1). So this is the correct optionFind the length of "C" using the Pythagorean Theorem. 14 48
