its a counterclockwise rotation of 90° about the origin.
Step-by-step explanation:
Answer:
Shift cos 0.9272
Gives 21.99 degrees near to 22
Answer:
7.7
Step-by-step explanation: We are trying to find side c or side AB
Using the law of sines formula,
a/sin a= b/sin b c/sin c we can solve for missing side.
We are given side BC or side a which is 11
We also are given angle A is 82 degrees
Angle C is 44 degrees also.
So let set up a proportion.
11/sin 82= x/sin 44
11/sin 82× sin 44=x
x= 7.7
Volume of Cylinder V₁ =πR². H
Volume of a cone V₂ = (1/3).πR².h
We know that H=4h (given) & R, the radius =75 &The total Volume = V₁+V₂,
We also know that the hopper has one cylinder & 2 equal cones
Hence
πR². H + 2 [(1/3).πR².h] =343,000 ft³
π(75)².H + 2[(1/3).π(75)².h] =343,000
But H = 4h, then
π(75)².4h + 2[(1/3).π(75)².h] =343,000. Solve for h
26250.π.h = 81,466.8.h = 343,000
& h=343,000/81,466.8, ==> h=4.16 ft & H =16.6 FT
Answer:
19+19+10+10= 58 is the answer
