Question

one of the angles of a triangle is half the sum of other two angles find the angle

Answer 1

Hey MATE!

Let the angles of triangle be x, y, z.

Therefore :

x + y + z = 180 --------1 equation


Now it is given :

$x = \frac{1}{2} (y + z) \\ 2x = y + z$
Now we put value of (y + z) in equation 1 from here ;

x + 2x = 180

3x = 180

x = 180/3

x = 60°

Hope it helps
