Question

The first angle of a triangle is 23° more than the 2nd angle. The 3rd angle of a triangle is 6 times the 2nd angle. Use X to represent the unknown value

Answer 1

I assume you mean to let x represent the "second" angle. So, we have

x+23 + x + 6x = 180
Now just solve for x.

After that, I assume you are supposed to indicate the measure of each of the angles...
