Answer:
5. 6.1 units
6. 29.4 units
7. 12.8 units
8. 29.1 units
Step-by-step explanation:
5. We have the opposite and adjacent sides here for angle 21 degrees. So we need to use tangent, which is opposite / adjacent:

≈ 6.1 units
6. We have the opposite and hypotenuse sides here for angle 33 degrees. So we need to use sine, which is opposite / hypotenuse:

≈ 29.4 units
7. We have the opposite and adjacent sides here for angle 37 degrees. So we need to use tangent, which is opposite / adjacent:

≈ 12.8 units
8. We have the opposite and hypotenuse sides here for angle 31 degrees. So we need to use sine, which is opposite / hypotenuse:

≈ 29.1 units
Hope this helps!
The rule for a 90 degree rotation is
(x,y)——>(-y,x)
So let’s take the coordinate (-5,-1) and let’s replace the x and y places together!!!
So that would give us -1•-1 which is just 1
Then -5•1 which is just -5
So the answer is
(1,-5)
The answer would be 32,000.
To find the circumference you use c = pi d. Radius * 2 = Diameter
c = 3.14(36)
c = 113.04 in. square.
