The square below has an area of 4 - 40 + e- square meters.
what expression represents the length of one side of the square?
side length
4- 4x + 2?
side length =
merers

answer:

step-by-step explanation:

correct

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
