An acute angle θ is in a right triangle with sin θ = seven eighths. What is the value of cot θ?

1 answer:

7 0

Sin = opposite/hypotenuse, so one side is 7 and the other is 8.
sqrt(64-49)=sqrt(15) which is the third side, and tangeant = opposite/adjacent, which is 7/sqrt(15). Cotangeant is 1/tangeant, so it would be sqrt(15)/7
