Question

measurement of angle EFH is equal to 7 x + 2 and measurement of angle EHG is equal to 12x + 30 what is X?

Answer 1

The altitude of the triangle intercepts perpendicularly
meaning that the angle EHG equals to 90 degrees
so....
12x + 30 = 90
subtract 30 from both sides
12x = 60
divide both sides by 12
x = 5

Hope this helps
