Answer: D

Step-by-step explanation: By using SOH for sin A, 'S' being sin, 'O' being opposite side of angle A and 'H' being the hypotenuse which is the longest part of the triangle you would find that 15 is opposite from Sin A and 17 the hypotenuse, 15/17.

For cos A you would use CAH, C= cos, A which is the adjacent of the triangle located next to angel A which is 8, and H= hypotenuse (also note that the hypotenuse never changes even if the angle may be different) CAH would be cos A = 8/17

HELP!!!!!!!!!!!!!! I learned this two years ago and I don't remember how to do this anymore!!!!!!

Otrada [13]

So remember the acronym "SOH CAH TOA"

Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent

Opposite = Side that doesn't touch the angle
Adjacent = Side that touches the angle
Hypotenuse = Side that is across from the right angle

So we see that side a doesn't touch angle $\alpha$ , hence making it the opposite side. And we see that side b is across from the right angle, making it the hypotenuse. <u>Using this info, $\sin \alpha = \frac{a}{b}$ </u>

So we already know from part A that side b is the hypotenuse. And also since side c touches the angle, it is the adjacent.<u> Using this info, $\cos \alpha = \frac{c}{b}$ </u>

Next, it has been established that side c is the adjacent and side a is the opposite side. <u>Using this info, $\tan \alpha = \frac{a}{c}$ </u>
