Answer 16

Hiya!
(pun intended)

We have a right angle triangle. Let's first find the third side of the triangle.

Do you know the Pythagorean theorem?

Answer 17

a and b would be the two legs

c would be the hypotenuse

so then you would have
a^2 + b^2 = c^2

In your image, you have a hypotenuse (or c) of 20
And one of the legs is 16, so what would the other value be?

16^2 + b^2 = 20^2

b = ??

Answer 18

Now for the actual questions of finding sin A, cos A, and tan A

Have you ever heard of SOH CAH TOA

Essentially, it's an acronym to help you remember the trigonometric functions

sin of an angle equals the opposite side over the hypotenuse

We write that as
sin \(\theta\) = opposite/hypotenuse

Do you see the initials?
Sin = Opposite/ Hypotenuse

SOH

Similarly, for cosine and tangent

cos \(\theta\) = adjacent/hypotenuse

CAH

tan \(\theta\) = opposite/adjacent
