anyway thanks in advance have a great afternoon (or whatever time it is where you live) :]

Answer 1

are you trying to find the length of AC ?

Answer 2

no.. I'm trying to find the measure of the angle A

Answer 3

ok use SOH CAH TOA

Answer 4

I already did my equation above like I was told to ^ not sure if I did it right but I did it.

Answer 5

So I do it using
sin = opposite/hypotenuse
and not using
cosec 0 = hypotenuse/opposite?

I know how to solve it but I don't know which one to use (hope that made sense)

Answer 6

use sin

Answer 7

cos will give u angle of C

Answer 8

but your missing the bottom length of AC so it wont work.

Answer 9

Okay I did it right the first time then. Okay well my first answer was 0.006981260298
how do I round this to the nearest tenth?
I don't need to find AC it's not asked yet.

Answer 10

It tells me to find the measure of angle A and B first and then it asks me to find the length of AC but I already know how to do that I'm just stuck on the angles.

Answer 11

so the <A is 24 degrees.

Answer 12

how did you get that answer?

Answer 13

sin^-1(2/5) => 24 deg

Answer 14

OMG I totally forgot about that xD OMG I'm laughing so hard i forgot you have to turn 4 -> 2 and 10 -> 5
so WOW of me thank you! That explains why I kept getting a weird answer XD

alright one last question for angle B would it also be sin? @arjund12

Answer 15

just do <B = 90 - <A

Answer 16

so you get <B = 90 - 24 => 66 deg

Answer 17

okay yeah but I have to show my work and which I chose so I need to pick sin, cos, tan, etc..

Answer 18

use cos because you have adj and hypo lengths.

Answer 19

alrighty thanks so much!! :] have a great day/night/afternoon/evening/morning

Answer 20

thanks you to.
