Question

Find the x in the given triangle, step by step explanation please ​

Answer 1

Every triangle is equal to 180 so add 45 and the other number then subtract from 180 to get x

Answer 2

x = 42.67

Explanation:

x + 2x + 7 + 45 = (3 - 2) * 180

3x + 52 = 180

- 52 - 52

3x = 128

/ 3 / 3

x = 42.67
