Which trig ratio should you use to find the given side?
Sine
Tangent
Cosine

a. sine

Step-by-step explanation:

As it can be seen from the figure, triangle ABC is the right-angled triangle with Angle C is equal to 90 degree.

In a right-angled triangle, there is a formula as following:

+) sine (an acute angle) = (length of its opposite side)/ hypotenuse

In the figure, angle B and length of the hypotenuse are given.

As x is the length of AC and AC is the opposite side to angle B

=> So that we can use sine to find x

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
