Question

find the value of the unknown exterior angle x​

Answer 1

Answer

sorry, my bad, in the picture its interior angle, I thought it was exterior by reading

Step-by-step explanation,

First, Find the Angle sum of the sides (Shown- Triangle)

3-2×180= 180°

Then use it to find the unknown X

x+x+50= 180°

Transversing 50 to 180

180-50= 130°

The x+x becomes 2x.

so Keep x and transverse 2.

which is 130/2 = 65°

(Check 65)

+65

130

The unknown angles are 65°
