Answer:
Solution1 :
Let the RQ be x cm,
In right angle triangle PQR,
h^2\ =\ b^2+p^2h
2
= b
2
+p
2
QR^2\ =\ PQ^2\ +PR^2\QR
2
= PQ
2
+PR
2
x^2=\ \left(10\right)^2+\left(24\right)^2x
2
= (10)
2
+(24)
2
x^2\ =\ 100\ +576x
2
= 100 +576
x\ =\ \sqrt{100+576}x =
100+576
x\ =\ \sqrt{676}x =
676
x = 26 cm
Thus, the length of QR is 26cm.

Explanation:
Mean = total data ÷ number of data
=(15 + 120 + 50 + 100 + 80 + 10 + 15 + 8 + 10 + 15)÷10
= 423 ÷ 100
= 4.23
Mode = most repeated data
= 15
Median
Arrange the data in ascending order
8 10 10 15 15 15 50 80 100 120
Find the middle number
(15 + 15) ÷ 2
= 15
