Answer 3

lol please just answer if you know the answer @Shay17

Answer 4

Sorry I was busy in other question.

How about you give it a try ?

Answer 5

Please you give it a try .

Answer 6

I am busy in other question.

Answer 7

Umm ok so the angles always add up to 180 degrees
So you know one angle is 90 degrees already

Answer 8

thanks!

Answer 9

We are solving by SSS

Answer 10

solving by what?

Answer 11

the choices are
71.1
18.9
29.2
90

Answer 12

I was trying to explain how to solve just wait

Answer 13

@Shay17 Use trigonometry, you can obtain sin A. Find out the value of sin A and then calculate the sin inverse of that value.

Answer 14

SOH...
Sine: sin(θ) = Opposite / Hypotenuse
CAH...
Cosine: cos(θ) = Adjacent / Hypotenuse
TOA
Tangent: tan(θ) = Opposite / Adjacent

Shouldn't you use sin and cos to find angles A and B

Answer 15

@vishweshshrimali5

Answer 16

yeah

Answer 17

Ok so ...

Answer 18

There is no need to find out cos B as it will be equal to sin A

Answer 19

You only need to find out sin A.

Answer 20

@ashleychase1 are you familiar with these terms ?

Answer 21

sin = opposite / hypotenuse so 12/37

Answer 22

@vishweshshrimali5 ???

Answer 23

@ashleychase1 , please answer @Shay17 's question.

Answer 24

I think the user just left leaving us alone and closed the question.

Answer 25

ok that's fine I still want to know

Answer 26

Well you calculated sin A perfectly .

Now you have sin A = 12/37

\[\implies A = sin^{-1}{\cfrac{12}{37}}\]

Answer 27

Which is about 18.9 degrees .

Answer 28

SO B is correct.

Answer 29

Yup that's what I calculated as well : ) Ok

Answer 30

thanks!! @vishweshshrimali5 @Shay17

Answer 31

No problem @ashleychase1 and great work @Shay17 . :)

Bye friends
