Answer:
So, this triangle PQR can be broken into two right triangles, PNQ and PNR, with legs PQ = 39, PN =15, and QN = ? and PR = 17, PN = 15, and NR =? respectively.
Let's solve for what is easier first:
Since we know that 5-15-17 is a Pythagorean triplet, we can infer that NR is 5....like I said earlier, it is a right triangle, so this guess holds true.
Here comes the interesting part:
Now, we have one part of QR, which is QN.
The other part can be solved by using the Pythagorean theorem.
It is (39^2-15^2)^(1/2)..which gives you 36, the square root of 1296, which happens to be the difference between the squares of 15 and 39.
SO, QR = QN + NR
5+36 = 41
QR = 41.
Hope this helps!

Four hundred three and six hundred eight thousandths.
First use the formula 3.14 times radius squared to figure out the area of each circle.
The figure out the fraction of each circle that is highlighted and find out the area of that percent)
(e. x. 51 degrees out of 360 degrees = 14% 14% of the area of the circle is about 39.4)
Answer:
acircle has infintely many axes of symmetry
Step-by-step explanation:
H= 92 and h and f equal the same cuz they’re congruent (i think is the right term) so 5x+4=92 so x would be 17.6
