Question

Degree measures of three angles of a triangle are X Y and Z, Z = X + Y upon 2 then find the value of Z

Answer 1

Answer:

Step-by-step explanation:

Given angles of triangle are x, y and z Also z = (x + y)/2 ⇒ x + y = 2z → (1) Recall that the sum of angles in a triangle is 180° Hence x + y + z = 180° ⇒ 2z + z = 180° [From (1)] ⇒ 3z = 180° ∴ z = 60°
