-8y=24
We want to isolate y to get the value of 1y. Divide both sides by -8
y= -3
Final answer: y=-3

This is the associative property of addition (D).
It states that when adding three terms, the sum is equal no matter the grouping (parentheses).
let's recall that an isosceles triangle has two twin sides.
Check the picture below.
These are the parameters, whats the question?
Answer:
arc AM = 114°
Step-by-step explanation:
the measure of a tangent- chord angle is half the measure of its intercepted arc, that is
∠ MAC = 
(AM )
57° = AM ( multiply both sides by 2 to clear the fraction )
114° = AM
