Natasha runs all the way around the edge of her backyard. Her back-yard is 11 feet wide and 15 feet long. How far does Natasha run?

The answer is 52

Step-by-step explanation:

This problem is perimeter so you add 11 plus 11 plus 15 plus 15 to get 52.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
