Question

What is the value of X? Make sure to show all of your work! Hint: What does each angle measure in an equilateral triangle? You don't need to use the equation with Y at all.

Answer 1

Answer: X = 9

Show Your Work:
All Angles & Sides = 60.
All Triangles = 180.
60 x 3 = 180.

Angle N:
7x - 3 = 60
7 * 9 - 3 = 60.
