Answer:
Every angle listed is 90 degrees
Step-by-step explanation:
First of all, we know that the angle with the red square is 90 degrees; that square is a symbol that represents right angles. If that angle is 90 that must mean that line t and line a are perpendicular. In a perpendicular intersection, 4 right angles are created. Additionally, since line b is parallel to line a; it must also be perpendicular with line t. Therefore, all of those angles are also 90 degrees.
The answer can also be found using the properties of 2 parallel lines and a transversal like corresponding angles and alternate side interior angles.

You need to rewrite this equation and then i can help
PEMDAS
We start with exponents.
4 x 4 is 16
12 divided by 3 is 4
4 times 5 is 20
20-16 is 4
4 is the answer.
Answer:
V = 18816.57 in^3
Step-by-step explanation:
So we need to find the volume of the inner sphere. Try to picture the coconut as a circle with another circle inside of it. We know that the bigger circle is 55 inches wide, and the distance between the circumferences of the circles is 11 inches. that means the inner circle is 55 - 2(11) inches wide. This is because we have 11 inches of coconut meat on either side of the inner circle.
55 - 2(11) = 33 inches
The radius is half of the diameter, so r = 16.5 inches.
Now just use the formaula V = 
V = (4/3) * 3.14 * (16.5)^3
V = 18816.57 in^3
<em>Also, just a side note.. this is one big coconut..</em>
