Question

In triangle ABC, AB = 7 and AC = 17. Find m 13 years ago

Answer 1

tan x = 17 / 7
x = arctan 17/7

Answer 2

Okay...well I'm assuming you know the trig functions....well here you will have to use the inverse trig functions

sun^-1 , cos^-1 , and tan^-1

You use these when you have sides...but want to find angles.....just like you use sin, cos, and tan when you have an angle and a side and you want to find the other side...

So...you have some angle *m*...a side opposite that angle....and a side adjacent to that angle..sounds like a tangent function...so this can be set up as

\[\tan^{-1} \frac{ 17 }{ 7 } = ?\]
