Question

Determine angle theta:
Cos theta = 0.1392
Tan theta = 0.6249

Answer 1

Take the inverse of each...your calculator should have a cos^-1 and tan^-1 function.

Answer 2

Do what?

Answer 3

Ohh, okay.

Answer 4

Thank you, How do i do these: Sec 15 degree 30' determine the value

Answer 5

First, convert 15 degrees and 30' to decimal degrees:
\[15deg 30' = 15+30*\frac{1}{60}=15.5 degrees\]
Second, secant is equal to:\[sec \theta=\frac{1}{cos\theta}\]So \[sec \theta=\frac{1}{cos(15.5)}\]
