Question

The figure shows a triangular piece of cloth.

What is the length of the portion BC of the cloth?

7 cos 33°

sin 33 degrees by 7

7 sin 33°

cos 33 degrees by 7

Answer 1

Using what you told me from the last problem I think that the answer is 7 cos 33°

Answer 2

Answer 3

Not exactly if you remember SOH CAH TOA then you know that cos would be \[Cos \angle = Adjacent/Hypotenuse\]

Answer 4

If we use the angle 33 we want to solve the side opposite of that and we only have the hypotenuse

Answer 5

So the adjacent side would not work in this example

Answer 6

Ohh. Then it would be 7 sin 33° because sine is opposite/hypotenuse right?

Answer 7

Correct! Great Job

Answer 8

Yes. Thank you!
