Answer: 63 degrees (second choice)
The two angles shown are corresponding angles. They are both on the bottom side of their adjacent parallel line, and at the same time, they are also on the left side of the transversal line. This is why they are corresponding angles.
Corresponding angles are congruent if you have a set of parallel lines like the diagram shows. So that's why a = 63.

When Ф lies in quadrant IV the value of cos Ф lies in [0, 1].
<h3>What is quadrant?</h3>
One fourth of the part of a circle is said to be the quadrant of the circle.
Given the angle Ф lies in quadrant IV.
As we know, cos Ф is positive only in first and fourth quadrant i.e when Ф lies in 0<Ф<90 and 270<Ф<360.
cosФ range from [-1,1]
So, cos Ф is positive when Ф lies in 1st and 4th quadrant.
& cos Ф is negative when Ф lies in 2nd and 3rd quadrant.
If cos ∅ lies in the quadrant IV, anything between [0, 1] can be the value of cos ∅.
Hence, when Ф lies in quadrant IV the value of cos Ф lies in [0, 1].

16.25pi
You can get this by first solving for volume of a cylender formula for the 1.5 radius of the outer shell. Then solve for a 1 radius of the inner empty portion. Then subtract the second from the first.
Answer:
40, 50, and 90
Step-by-step explanation:
You know that there are 180 degrees in a triangle, so you'd use the ratio to find each angle by setting up your equation like this: 4x+5x+9x=180
Then, simplify the equation and solve for x:
Then, plug 10 into each x value to find each angle measure:
4(10)=40, 5(10)=50, 9(10)=90
