Best ResponseYou've already chosen the best response.1hmmm to find 3rd side you should know one angle and one side sin = opposite over hyp right ?

Best ResponseYou've already chosen the best response.0but the hypotenuse isn't known in this case

Best ResponseYou've already chosen the best response.1right i want u to take a few sec and think about is it sin 13 = 5 /c correct ? sin = opposite over hyp and we are looking at angle B which is 13

Best ResponseYou've already chosen the best response.0no it's not correct! :) I was looking at angle A

Best ResponseYou've already chosen the best response.0but we can find out what angle b is.. it's 77 degrees

Best ResponseYou've already chosen the best response.1dw:1443995567775:dw we don't konw what c equal to and we don't know what is B so you can't use sin for angle B

Best ResponseYou've already chosen the best response.1nvm that's correct tan B = b/5

Best ResponseYou've already chosen the best response.0so should i write 5tan(77)?

Best ResponseYou've already chosen the best response.1well 77+90 =167 subtract from 180 180167 =13 dw:1443996138575:dw looks right

Best ResponseYou've already chosen the best response.1or maybe they want u to use given angle which si 77 to finfd length c
