Question

Q.6 The sum of two angles of a triangle is equal to its third angle. Determine the
measure of the third angle.
(3x 20)
(4- 367)​

Answer 1

Answer:

90°

Explanation:

the sum of all angles of a triangle is 180°

so, take the sum of angles as x+y+z=180°

take x is first angle , y is second angle and z is the third angle

given x+y = z , so z+z =180°

2z = 180° , so z = 180/2

z = 90°
