Question

please tell the answer​

Answer 1

Answer:

(x+3)+(x+20)+(x+7)=180 ( straight line)

x+x+x+3+20+7 = 180

3x + 30 = 180

3x = 180 - 30

x = 150

3

x = 50

Answer 2

Answer:

53°,70°&57°

Step-by-step explanation:

This is straight angle so it measures 180°

(x+3)°+(x+20)°+(x+7)°=180°

x°+3°+x°+20°+x°+7°=180°

3x°+30°=180°

3x°=180°-30°

3x°=150°

x=150°/3°

x=50°

1st angle=50°+3°=53°

2nd angle=50°+20°=70°

3rd angle=50°+7°=57°
