Question

PLEASE HELP! :D

What is the value of x?

Enter your answer in the box.

Answer 1

x = 39°

Explanation:

The sum of the 3 angles in a triangle = 180°

To find x, subtract the sum of the 2 marked angles from 180

x = 180° - (39 + 102 )° = 180° - 141° = 39°

Answer 2

x=39

Explanation:

The angles inside of a triangle are all meant to equal 180. Therefore you would add 102 and 39 together to get 141. You would then subtract this number from 180 to get 39.
