how would I solve this

Answer:
5√5
Step-by-step explanation:
Hypotenuse (h) = 15
perpendicular (p) = 10
base (b) = ?
We know by using Pythagoras theorem
b = √h² - p²
= √ 15² - 10²
= √ 125
= 5√5
Hope it will help :)
Answer:
≈11.2
Step-by-step explanation:
a²+b²=c²
10²+b²=15²
100+b=225
-100 on both sides
b= √125= 11.2
