Question

The angles of traingle are (x+10°),(2x-30°) and x°. Find the value of x

Answer 1

Here is the answer..  Sum of all angles of triangle is 180°.
According to the given condition,
l(x + 10) +( 2x - 30) +( x )= 180°
4x -20 = 180°
4x = 180° + 20°
4x = 200°
x = 50°

Hence,  Value of x is 50°.

Value of (x+10) = 50+10= 60°

Value of 2x - 30 = 2× 50 - 30 = 100 - 30 = 70°

Value of x = 50°

 Hence, the angles are 60° , 70° and 50 °.
