Question

write the sine, cosine, and tangent ratios for 11 years ago

Answer 1

the base is 48in.

Answer 2

Which one is angle A

Answer 3

the right angle?

Answer 4

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

Answer 5

I will assume angle A is the one at the base of the ramp, since you labeled the vertical side the opposite side.

Answer 6

You first have to calculate what the length of the hypotenuse is, using the pythagorean theorem...
\[(hypotenuse)^2=36^3+48^2\]

Answer 7

hypotenuse^2=46656+2304
=48960
sqrt48960
=221.3

Answer 8

A^2 + B^2 = C^2

I think i typed a 36^3 on accident..

Answer 9

\[hypotenuse = \sqrt{48^2+36^2} = 60\]

Answer 10

ok I thought that was weird lol.

Answer 11

ok sin(A)= 36/60?

Answer 12

@DanJS

Answer 13

yes

Answer 14

wait ok I'm not sure how to do that @DanJS

Answer 15

@Directrix can you help me?

Answer 16

What did you get for the hypotenuse?

Answer 17

60
