Question

The angles of a triangle are(x+21)degree, X degree and (2x-45)degree. Find the value of x

Answer 1

Hii..

here is ur answer :--

Given,

Angles of a triangle = (x+2)degree , x degree, (2x-45)degree

We know that sum of the interior angles of triangle is 180 degree

so,

(x+21)+x+(2x-45) =180 degree

=> 4x -24 = 180 degree

=> 4x = 180degree -24 degree

=> 4x = 156 degree

=> x = 156/4

=> x =39 degree
