Answer 3

right okay ill give it another go

Answer 4

Alakara you are wrong. That should be
\[\sin 37\]

Answer 5

would i have to do the hypotenuse divided by the adjacent angle so cos37?

Answer 6

You need to use sin if you want to find out the opposite side.
Cos if you need the adjacent side.
AB is the opposite, so use sin37.

Answer 7

right one second ill probably need more help

Answer 8

You should arrive to AB=3.4905

Answer 9

0.549022 is what i got from sin37

Answer 10

0.60181 according to my calculator

Answer 11

oh dear, ill go with yours, then do i divide it by 5.8?

Answer 12

Make sure that your calculator uses degrees and not radians

Answer 13

multiply i mean?

Answer 14

oh i had it on the radians one i think

Answer 15

Yep 5.8*sin37=ABside

Answer 16

Thankyou
