Question

 If x+ 3 , x+20, x+7 forms a linear pair then find value of x​

Answer 1

Answer:

A.T.Q.

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

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

=> 3x+23+7 = 180

=> 3x+30 = 180

=> 3x = 180 - 30

=> 3x = 150

=> x = 150/3

=> x = 50

Answer 2

Answer:

(x+ 3) + (x+20) + (x+7) = 180°

x+ 3 + x+20 + x+7 = 180°

3x + 30 = 180°

3x = 180 - 30

3x = 150

x = $\frac{150}{3}$

x = 50

∠1st = 50 + 3 = 53°

∠2nd = 50 + 20 = 70°

∠3rd = 50 + 7 = 57°
