Answer:
13
Step-by-step explanation:
base = 5
height = 4
hypotenuse = sqrt ( 5^2 +4^2) = sqrt(25+16) = sqrt(41)
5+4 = 9
so perimeter = 9+ sqrt(41)
answer is the 3rd one.
We know that
In any quadrilateral where the vertices are on the circumference of a circle, the opposite angles add up to

degrees.
So,
in this problem

therefore
the answer is
A. 25.2 because it is the only answer outside of the previous range of 25.6 - 29.1.
You are multiplying the 3x by 6
the last choice is correct
