THe first thing we need to do is find the hypotenuse. From the tangent we know that the legs of the right triangle are 3 and 4. So this 2/3 of a special right triangle (3-4-5). Thus the hypotenuse is 5. The sin is defined as

. We know the opposite is 4 and hypotenuse is 5. Thus the sin is
Answer:
So first you have 5(8x+3)
And then you simplify it:
5(8x)=40x
5(3)=15
And then you get 40x+15
