Question

MEDAL +FANcan someone please find a

Answer 1

a = 12*cos(90-20)

Answer 2

Or a bit more simply, use sine of the 20 degree angle.

Answer 3

1079 i dont think thts right

Answer 4

Definitely too big. The hypotenuse of a right triangle is the longest side, so it has to be shorter than 12.

Answer 5

11.2 :)

Answer 6

This is the process, Raz.
1) Identify, based on the angle you know, which side is the HYPOTENUSE, which side is OPPOSITE from the angle, and which side is ADJACENT to the angle.

Answer 7

a=12sin(20degrees)

Answer 8

Does that much make sense so far? Do you see why I labeled those sides that way?

Answer 9

yup

Answer 10

Okay, cool. Now step 2, you look at the sides you're working with and decide which trig function to use out of Sine Cosine and Tangent.

We know the hypotenuse, and we want to know the opposite.

Answer 11

Now, do you know the definitions of the three basic trig functions? Maybe you memorized them by SohCahToa?
