Question 3.
X and Y are
supplementary angles. Given X=72°, find the value of Y.

Step-by-step explanation:

Since X and Y are supplementary angles it means that the sum of their angles add up to 180°

To find Y , add X and Y and equate it to 180° and solve

That's

X + Y = 180

Y = 180 - X

X = 72°

Y = 180 - 72

We have the final answer as
