Question

Can someone please check my answer please?

The picture below shows a right triangle shaped charging stand for a gaming system. Which expression shows the length of side AB?


I used cos, and set up the equation 8cos(60.

im not sure what answer choice this is.

POSSIBLE ANSWERS:

8 cosec 60°

8/sin60

8/cos60

8 tan 60

Answer 1

@zepp can you check my answer please

Answer 2

This is Hypotenuse/Adjacent too, secant.

Answer 3

Umm, no secant so cosine then :D

Cos(60)=8/AB
AB=8/cos(60)

Answer 4

i just edited the answers^^

Answer 5

That's right, \(\large \frac{8}{\cos(60)}\)

Answer 6

so 8 cosec 60?

Answer 7

oh, nvm i just saw it

Answer 8

thank you!

Answer 9

cosec is reciprocal of sin

Answer 10

If you want to write it in the other format, it would be \(8\sec(60)\)

Answer 11

ok, thank you. i always get cosec confused with cos

Answer 12

Since \(\large \frac{1}{\cos(x)}=\sec(x)\)

Answer 13

but the answer is 8/cos60, correct?

Answer 14

Correct.

Answer 15

thank you :)
