Answer:

Step-by-step explanation:

The sum of a triangle's interior angles is 180

. From the figure, we can see that one of the angles is a right angle. The remaining two are x and y. By adding these together, we can equate their sum with 180.

x+y+90=180b

Using the equation found in part A and the given equation, we can form a system of equations.
