Answer:

a = 98⁰

Step-by-step explanation:

According to the the triangle sum thereom, all angles in triangle add up to 180⁰.

m<a + m<b + m<c = 180⁰

m<a + <u>34⁰ + 48⁰</u> = 180⁰

m<a + 82⁰ = 180⁰

m<a + <u>82⁰ - 82⁰</u> = <u>180⁰ - 82⁰</u>

m<a = 98⁰

Hope this helps, thank you :) !!

answer these BOTH. PLEASE! if u answer both correctly i'll give u brainliest and extra points please please please.
Reil [10]

<u>Answer:</u>

9. x = 12

10. x = 31

<u>Step-by-step explanation:</u>

9. Corresponding angles are equal, so technically you can move that (7x - 20) to be diagonal with the (4x + 16). Along with the corresponding angle, diagonal angles are equal to each other. Therefore you can set (7x - 20) equal to (4x + 16) to find x.

7x - 20 = 4x + 16

Solve

3x - 20 = 16

3x = 36

x = 12

Therefore x is equal to 12

<u>Check:</u>

4(12) + 16

= 64

7(12) - 20

= 64

10. All angles in a triangle have to add up to 180 degrees. Therefore, you can write your equation like this:

x + 2x + 25 + 2x = 180

Combine like terms

5x + 25 = 180

Solve

5x = 155

x = 31

Therefore, x = 31.

<u>Check:</u>

31 + 2(31) + 25 + 2(31) = 180

31 + 62 + 25 + 62 = 180

180 = 180

<em>I hope this helps!!</em>

PLSSS HELP IMMA FAIL
Nutka1998 [239]

Answer:

x = 10

Step-by-step explanation:

X = 10 because if you look at the 28 and 14, 14 is half of 28 so the ratio is 1:2 which would also work for the 20 so the answer is 10
