The Nelson family invests $6,000 into an account that earns 4.85% annual interest. They deposit an additional $175 each month. At the end of 5 years, will the value in the account be enough to pay for at least the first year of college?

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
