Question

Help ! need an explanation and answer!

Answer 1

as below

Explanation:

because the interior angles add up to 180 degrees.. you can solve this

180= 32 + 64 + x hmm

84 = x

so the last angle is 84° :)

Answer 2

as we know that the sum of three interiors angle = 180

Two angles are given 32 and 64

let the angles be a , b and c

A + B + C = 180

32 + 64 + C = 180

C = 180-96

C = 84

Hence the 3rd angle is 84
