Answer:
The area of the cross section would be 160in squared
Step-by-step explanation:
They are asking for the area of the cross section, the rectangle that is splitting the prism in half. Area=heightxwidth. So, you would just multiply 10x16 to get your answer, which would be 160.
Answer:
3/7 and 4/14

Answer:
Step-by-step explanation:
The given trigonometric equation is
for 
.
We divide through by 5 to get;
We take the inverse tangent of both sides to obtain;
Since the tangent ratio is positive, it means 
could also be in the 3rd quadrant. But this is outside the given range.
Therefore the correct answer is A
