Question

Having trouble understanding this.

Answer 1

The square that you see at the bottom means 90 degrees

The outside angle (in this case "x") is equal to 90 + 52 which is 142 degrees

Answer 2

x=142 degrees

Explanation:

we know that a triangle adds up to 180 degrees, so we know 2 angles already which are 90 and 52 so we subtract them

180-90-52= 38

so 38 is the missing angle and we need to find the angle outside so we subtract 38 from 180

180-38= 142

so x=142
