a. 12
b. 12 radical2
c. 12 radical3
d. 24 radical2

Answer 1

What trigonometric function relates the angle, the opposite side, and the hypotenuse of a right triangle?

Answer 2

sin

Answer 3

i tried and i got a negative number

Answer 4

Okay, so the sin (60) = NO / 24

Answer 5

NO = 24 * sin(60)

Answer 6

Your calculator is probably in radian mode.

Answer 7

It either needs to be in degrees or you need to convert 60 to radians.

Answer 8

Because sin(60) = sqrt(3) / 2

Answer 9

Which means 24 times that is 12sqrt(3)

Answer 10

thank you. i changed it to degree mode. it was in radian mode

Answer 11

Common error. :) Mine was too and I had to switch it.

Answer 12

i got c

Answer 13

thanks. i gave you a medal

Answer 14

Take care.
