Edgar is scuba diving 50 ft below the water. He is swimming to the surface at a rate of 3 ft per second. Write an equation to represent his death, d, after s seconds.

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

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?
