Question

The angles of a triangle are (x + 10°), (2x − 30°) and x°.Find the value of x

help plz... to do ​

Answer 1

Answer:

According to the question,

The sum of all angles in a triangle = 180°

So, x+10+2x-30+x =180.

So, 4x-20 = 180°

Therefore, 4x = 180°+20 = 200°

So, x=200/4 =50°

Therefore, x = 50.
