Question

What is the measure of angle A in the triangle below?

Answer 1

this is the triangle

Answer 2

There are 3 ways to get it.

tan(A) = 12/35

or

cos(A) = 35/37

or

sin(A) = 12/37


Do you understand trignometry? This is just formula applications

Answer 3

I really don't understand it all the much... I just started it, really

Answer 4

Ok so

\[\tan (A) = \frac{ opposite }{ adjacent } = \frac{ 12 }{ 35 }\]

\[\cos (A) = \frac{ adjacent }{ hypotenuset } = \frac{ 35 }{ 37 }\]

\[\sin (A) = \frac{ opposite }{ hypotenuse } = \frac{ 12 }{ 37 }\]

Answer 5

okay. I don't really know where to go from here I'm using tan(A) and I get .3428 what do I do now?

Answer 6

You want the angle. The angle is just the A.
By now you have

tan(A) = 0.3428

with some manipulation:

tan(A) = 0.3428
A = arctan (0.3428)

and that is your final answer! Don't forget to set your calculator into degrees and not radians

thank you!
