Question

An acute angle θ is in a right triangle with sin θ = eight ninths. What is the value of cot θ

Answer 1

well what you can do is arcsin both sides on the first equation to solve for theta

arcsin( sin θ )= arcsin ( eight ninths)
θ = arcsin ( eight ninths)

once you know theta you can plug it in to

cot θ

Answer 2

mmmmm so arsin 8 nithts to get theta?

Answer 3

is it \[\frac{ \sqrt{17} }{ 9 }\]
