If sin X = 0.3240 and b = 40, what is the value of c

123.46 or 42.28

Step-by-step explanation:

Assuming that b is the leg side of a triangle and that c is the hypotenuse, we can solve for c using SOHCAHTOA.

We can find the angle from the equation sin X = 0.3240.

X = 0.3240

X = ...

Through SOHCAHTOA, we know that we should use either sin X =  or that cos X = .

I'm going to assume that we use sin X = since we are given a length b and not a length a. So:

sin 18.9050 =

c =   = 123.46

If we use cos X = , then:

cos 18.9050 =

c =   = 42.28

Not sure which one is correct since we are not given a picture of the sides.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

answer: do we write it
