Asked by your mama

You are making a banner for your cousin's birthday party. You start by cutting out triangle pieces of cardstock paper; to not waste paper, you choose to cut the paper diagonally. Each piece of cardstock paper measures five inches in height with a base of three and a half inches. After cutting, what is the approximate angle formed at the base of the triangle?

Take the base as the adjacent side and the height as the opposite side of the right triangle. Then

tan θ = opposite/adjacent = 5 / 3.5 = 10/7.

θ = arctan(10/7) ≈ 55.0°.

So the base angle is approximately 55 degrees.
