In the diagram below, is parallel to . What is the value of y?

I don't remember this much...But i think since 180 degrees = a straight line... you subtract 180 degrees by 150 degrees. Therefore you will get 30 degrees. Which i believe is a acute angle if i'm correct. So answer A

Step-by-step explanation:

When lines are parallel, certain angles have certain properties. Same-side interior angles, as shown in the image, are supplementary. Supplementary angles are angles that add up to 180 degrees.

180 = y + 150

y = 30 degrees

The correct answer is A. 30.

Hope this helps!! :)

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
