Step 1: Add together the known angles.
Step 2: Subtract the sum from 180°.
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.

Answer:
21y² +34 yx + 8x²
Step-by-step explanation:
Area of a rectangle is given by L×W where L is length, and W is width
Given L=3y+4x
W=7y+2x
Area= (3y+4x) × (7y+2x)
3y(7y+2x) + 4x(7y+2x)
21y² + 6yx +28yx+8x²
21y² +34 yx + 8x²
Answer:
Dividing in unit form
9 ten thousand = 9 × 10000 = 90000
90000 ÷ 10 = 9000
Dividing the sum in Standard Form
90000 = 9 × 10⁵
10 = 10¹
[9 × 10⁵] ÷ 10¹ = 9 × 10
