Find value of X. Need help asap

Answer 1

Answer:

Angle sum property of triangle=180°

By angle sum property,

31°+(x-15)°+x°=180°

31°-15°+x+x=180°

16°+2x=180°

2x=180°-16°

2x=164°

x=164/2

x=82°

Answer 2

In a triangle the sum of three angles is equal to 180

$so \: here \: \\ 31 + (x - 15) + x = 180$

=>

$31 + 2x - 15 = 180$

=>

$2x + 16 = 180$

=>

$2x = 180 - 16 = 164$

=>

$x = 164 \div 2 = 82$
