-18 is 18 below the zero on a number line and 104 is 104 above the 0 on the number line. If you go from -18 toward the zero and continue to 104 it will give you 122 degrees. another way is to add 104 and 18. Hope that helps
Answer: this depends are you finding it for a shape or in general if it is in general you simply multiply and get 32,886
Step-by-step explanation:
F(3)=-4(3)+3=-9
g(3)=3(3)+4=13
f(3).g(3)=-9*13=-117
You can use the sin function to solve this.
Think of a triangle with the conveyor being the longest side (hypotenuse). The height (the vertical side) is H=17m. The angle of elevation is a=36.2. We are looking for length of the hypotenuse, L.
The sin is the ratio of height to hypotenuse: sin(36.2) = H/L = 17/L
Now solve for L:
L = 17/sin(36.2) = 17m/0.59 = 28.78m
The conveyor needs to be approx. 28.8m long to get close to the max. efficient angle.
