The given angles Y and Z are supplementary angles. The measure of angle is 50 degrees. The measure of angle is five times the va

Minchanka [31]

Answer:

x is 10°, expression of angle could be

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

Step-by-step 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
