Question

I've been working on this for 2+ hours, so frustrated, my last tutor got it wrong too.

solve using law of sines
please show all work​

Answer 1

20

Explanation:

sin(28) sin(x)

---------- = -----------

7 5

sin(28)* 5 = 7sin(x)

---------------------------

7

sin(28) * 5

---------------- = sin(x)

7

You have to seperate sin from (x). When you do that, it becomes inverse (sin^-1).

sin(28) * 5

sin^-1 (------------------) = x

7

Imput that into you calculator, and you should get 19.59302173 (20 to the nearest degree)

Hope this helps.
