Question

draw a right triangle that has leg with length 7 and a hypotenuse of 12. find the angle measure formed by those two sides. write angle to the nearest tenth.

Answer 1

So, thats out triangle,

to find the angle formed by those two sides, we use the cosine function

$\begin{gathered} \frac{7}{12}=\cos \theta \\ \theta=\cos ^{-1}(\frac{7}{12})=54.31^o\text{ }\approx54.3^o\text{ to the nearest tenth} \end{gathered}$
