Question

If x° and (x+20)° are the measures of two angles in linear pair ,then find the value of x.​

Answer 1

Answer:

Step-by-step explanation:

Sum of angles of linear pair=180°

then,

x°+x+20°=180

2x=180-20

2x=160

x=160/2

x=80° = ans

Hope it help u

Answer 2

Hey mate ☺

x°+x°+20=180°.....{linear pairs}

2x°+20°=180°

2(x°+ 10°) =180°

$x + 10 = \frac{180}{2} \\ x + 10 =90$

x=90-10

x=80°

Hope it helps you ☺✌✌
