Question

in the figure given below, find the value of x

Answer 1

according to your question___________________

(x+7), (x+7) and (x+ 20) are the angles.

SINCE THEY LIE ON THE SAME LINE THEY FORM A LINEAR PAIR HENCE THEIR SUM IS 180°

SO,

=> (X+7)+(X+20)+(X+7) = 180

=> 3X + 34 = 180°

=> 3x= 180- 34

=> 3x = 146

=> x= 146/3

=> x= 48.66°

Answer 2

A/Q (x+7)+(x+20)+(x+7) = 180° [Linear Pair]
=> x+7+x+20+x+7 = 180°
=> 3x+34 = 180°
=> 3x = 180°-34
=> x = 146/3
=> x = 48.66°

I hope the answer is correct.
