Question

Answer the question with complete working.

Answer 1

Answer:

50°

Step-by-step explanation:

Exterior Angle = Opposite interior angles of a triangle (Exterior Angle Property)

But it is given that,

Each of the interior angles is equal.

Let each of the interior angles be x.

A/q

x + x = 100°

2x = 100°

x = 50°

∴ Each of the interior angles measure 50°

Answer 2

Step-by-step explanation:

Exterior angle = sum of two opposite interior angles

$2x = 100 \\ x = 50$

Also sum of all angles of a triangle = 180

implies Angles are 50,50,80
