Answer:
D
Step-by-step explanation:
It is given in the question that, PA is a radius and AB is the tangent segment .
And in a circle, radius and tangent are always perpendicular, it means they form 90 degree with each other . Or angle PAB is a right angle .
And we cant say anything about the length s of PA and AB, neither of PA and PB.
So out of the four options, correct option is the third option .
Hello from MrBillDoesMath!
Answer:
4 sin(70) which is approximately 3.76
Discussion:
sin(70) =
side opposite angle/ hypotenuse =
?/4.
As sin(70) = ?/4, multiplying both sides by 4 gives
? =4 sin(70) which is approximately 3.76
Thank you,

The first option 0.65 might be right
Answer:
B) 
Step-by-step explanation:
That is a triangular prism and thus, it has two bases that are triangles, in this case, right triangles, whose hypotenuse is 5 in. long and one of its legs is 4 in. and the other one, 3 in.
The first step is to find the area of both bases like this:

The second step is to get the lateral area, which is compound of three rectangles, hence the process is the following:

Finally, we sum both of the areas found to calculate the total area.

So, the answer is option B).
