Question

Please help me find out the answer I am request you to find out the answer if you don't know the answer don't answer it and do all please​

Answer 1

Answer:

10. 4x + 2x = 120 ⁰ { sum of interior angles is equal to the exterior angle..}

6x = 120⁰

x = 20⁰

angle ACB = 40⁰

angle BAC = 80⁰

9. a. 77+60+ x = 180⁰

x = 180- 137

x = 43⁰

b. 72+ 40 + x = 180⁰

x = 180 - 112

x = 68⁰

5.) 5x + 3x = 120⁰

8x = 120

x = 15⁰

5 x = 75⁰

3x = 45⁰
