Answer:

sin θ =  15/17

Step-by-step explanation:

First we have to know how much the hypotenuse measures.

to take out the hypotenuse we will use pitagoras, with the following formula.

h^2 = c1^2 + c2^2

c1 = 8

c2 = 15

h^2 = 8^2 + 15^2

h^2 = 64 + 225

h = √ 289

h = 17

well to start we have to know the relationships between angles, legs and the hypotenuse.

a: adjacent

o: opposite

h: hypotenuse

sin θ = o/h

cos θ= a/h

tan θ = o/a

we want to know the sin of θ

sin θ = o/h

sin θ =  15/17

marin [14]
It is best to know whether the Fast Pax $39,500 salary is a gross salary or a net salary to make sure the amount you will get by working there. A net salary is a total amount of salary and benefits that you will get by working in a company and A gross salary is the amount of the salary only excluding the other benefits. These terms are important for employees to consider
