These two are the problems i need with

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

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50
