Question

How would I find this? Would I do 90-40 and then get 50 or would I have to do 90-50 to get x?

Answer 1

i think u have to use subtraction

Answer 2

x = 50

Explanation:

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

subtract the sum of the 2 given angles from 180 for x

x = 180 - (90 + 40) = 180 - 130 = 50
