Answer:
10
Step-by-step explanation:
Since m||n the sum of given angles is equal to 180 (they are supplementary)
6x + 10 + 10x + 10 = 180 add like terms
16x + 20 = 180 subtract 20 from from both sides
16x = 160 divide both sides by 16
x = 10
I think y and z = 45
D
Cause a square has all equal sides
y - 5 = -(x + 5)
y - 5 = -x - 5
y = -x
find only for x or?
I think the answer is c
Because it says at most? am I right
