Question

What is the value of x?

Answer 1

• x = 14

--------------------------

Use the triangle sum theorem, which states that the sum of the three interior angles is 180°.

Set up an equation and solve for x:

• 7x - 11 + 5x - 2 + 2x - 3 = 180
• 14x - 16 = 180
• 14x = 196
• x = 196/14
• x = 14
