Question

The sum of the angles of a triangle is 180 degree. if the three angle are (2x+15)degree,85degree and (x +20) degree, what is the value of x

Answer 1

Hola there...

According to the question,

Angle of the triangle are as follows :
(2x + 15)°, 85°, (x + 20)°

Sum of interior Angle of triangle = 180°

So,

=> 2x + 15 + 85 + x + 20 = 180

=> 3x + 120 = 180

=> 3x = 60

=> x = 20°. .....Ans

Hope this helps....:)

Answer 2

2x+15+x+20+85=180
3x+120=180
×=60÷3
x=20
