Question

Find the value of x,y,and z​

Answer 1

x = 30°, y = 15°, z= 150°

Explanation:

90 + x + 2x= 180 - Parts whole postulate

90 + 3x = 180

90 + 3x - 90 = 180 - 90

3x = 90

x = 30

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

x=2y - Alternate interior angles

30 = 2y

y = 15

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

2y + z = 180 - Parts whole postulate

30 + z = 180

30 + z - 30 = 180 - 30

z = 150
