Find the value of y in the diagram below

x=7 and y=12.

Step-by-step explanation:

If two lines intersect each other then vertical opposite angles are equal.

Divide both sides by 6.

The value of x is 7.

Same side interior angles are supplementary angles.

On further simplification we get

Divide both sides by 9.

Therefore, the value of y is 12.

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

i think is g(1)=-1.

hope that i can
