High School Geometry Test Question (Right Angle Trigonometry)

[AngelaM]

Hi. My 8th grade son is taking high school geometry and this was a question from his last test. His school is 100% remote and the teacher is difficult to contact. He is trying to submit test corrections but this one has him stumped. Any help is appreciated!

Use the Tangent definition.
`tan(theta)=y/x` where y = 1, x = d, and the given value of `theta`.

cot(θ) = d
