Question

Find the value of x , if these three angles are on a straight line form a linear pair (x+3)˚, (x+20)˚ and (x+7)˚.

Answer 1

Step-by-step explanation:

Here,

x + 3 + x + 20 + x + 7 = 180°

3x + 30° = 180°

3x = 150°

x= 50°

Answer 2

Answer:

x+3+x+20+x+7=180 3x+30=180

3x=180-30 3x=150 x=50 so x=50
