Question

Is it me or does Y have multiple awnser. If not I need help to find the awnser. I know that x=54.​

Answer 1

47.5

Explanation:

If r is parallel to s, then by the Alternate Exterior Angles Theorem:

x+56 = 3y-17. Additionally, (x+56)° is supplementary to (y+7)° because they make up a line.

So: 180 = x+56 + y+7 or

180-y-7 = x+56

Substitute into x+56 = 3y-17 so that 180-y-7 = 3y-17.

Solve for y to get y = 47.5

Answer 2

y doesn't have multiple awnser, y = 47.5

Explanation:

(y + 7) + (3y - 17) = 180

=> 4y = 190

=> y = 47.5
