Question

Please help me find the values of y and z .

Answer 1

y=120 and z=20

Explanation:

bringing (5z-40)° in their vertically opposite side

5z-40=60[being the pair of corresponding angle]

or, 5z=60+40

or, 5z=100

z=20

again,

5z-40+y=180[sum of straight angle]

or, 5×20-40+y=180

or, 100-40+y=180

or, y=180-60

y=120

Answer 2

Answer: Y=120 Z=20

Step-by-step explanation: this ones a little harder so im not too confident in these answers.. but hopefully they are also correct.
