Question

In the triangle below, determine the value of c.

Answer 1

ok you need to use your trig functions here.
SOH
CAH
TOA

Answer 2

Your given angle is C, and side c is opposite from that and you are also given the length of your hypotenuse. Since you have Opposite and Hypotenuse, you have the OH needed to use the sine function.

Answer 3

c/15=sin40

Answer 4

So to set it up you will have \[\sin(40)= c/15\]

Answer 5

Then solve for c by multiplying both sides by 15 to get

15sin(40) = c.

Answer 6

sashley0915 how can we get value of sin40

Answer 7

so is it 9.6?

Answer 8

Ya !

Answer 9

Yes! :)

Answer 10

I will try a method in which we don't have to calculate the value of sin40.

Answer 11

trying for aliter!:)

Answer 12

I will post later when I find it.
