Question

HELP PLEASE!!!!!! I'm about to run out of time and I cant figure this out.

The angles of a triangle are 128º, 5x + 10º, and 9xº. What is the value of x?

Answer 1

You should know that all three angles of a triangle add to 180 degrees, so use this formula:


`14x + 10 = 52`

Solve to get x = 3.
