Triangles and geometry

Question

A triangle has the angles W = 2x°+4° ,  Y = 5x°-3° and Z = x° +11°

Solve the equation to determine the value of x

Answer 1

You know that the sum of the angles must equal 180°.

 

W + Y + Z = 180°

 

(2x + 4) + (5x - 3) + (x + 11) = 180

 

Solve for x and finish from here.
