Question

The given angles Y and Z are supplementary angles. The measure of angle is 50 degrees. The measure of angle is five times the value of x. Write an expression for the measure of angleY. Find the value of x. What is the measure of angle​Y?

Answer 1

x is 10°, expression of angle could be

180 - z or 180 - 5x, the value of y is 130° if z is 50°

Explanation:

y + z is 180°

x is 50/5 = 10°

z is 50°

y is 180 - z = 180 - 50 = 130°

y can be 180 - 5x or 180 - z
