Since PQ // BC, ABC and APQ are similar triangles, so we can use the Thales theorem
AB / AP = AC / x it means 9/3 = x + 20/ x because AB=6+3=9
3= x+20) /x implies 3x = x +20, and 2x = 20, finally x= 20/2=10
x= 10
Answer:
I believe that the answer is A. It seems right to me.
Well i assume it is a quarter of a plate so what is the area of a quarter circle?
whole circum.=2*pi*r so a quarter = (2*pi*r)/4=(pi*r)/2 =25(given)
so pi*r=50....so r=50/pi put this in the area formula pi(50/pi)^2=2500/pi =796

Since we are working with a right triangle, we can use the Pythagorean Theorem, which states that:
Then, we are given the following information:
Let be "a" the shorter leg and "b" the the longer leg of the right triangle, so:
We can see that we need to perform the notable product, so:
We have that the obtained equation will be equal to 0 if: b is equal to 0 or b is equal to 28:
So, since we are looking for the side of a leg, the result that we need its 28 feet.
Hence, we have that the answers are:
