Assuming that a, b, and c are the angle of a triangle.

180° = a + b + c.

This is because the sum of all the angles in a triangle is 180°.

Now we plug in the value of the variables.

180° = 5x + 4x + x

180° = 10x

18° = x

Now that we know what x is we can plug it in:

a = 5(18°) = 90°

b = 4(18°) = 72°

c = (18°) = 18°
