Question

A. 60

B. 57

C. 29

D. 33

Answer 1

What is the question?

Answer 2

And I take it we're to find the measure of the angle?

You have an angle...a side adjacent to that angle...and the hypotenuse....use the COS function

\[\cos(x) = \frac{ 11 }{ 20 }\]

Now you want to find the angle...so use the ARCCOS function

\[x = \cos^{-1} \frac{ 11 }{ 20 }\]

*make sure your calculator is in degree mode*

Answer 3

I dont have a calculator with cos

Answer 4

You can calculate it in Google !
Type :
arccos (11/20)
