Answer:
son = 6 mother = 48
Step-by-step explanation:
Mother = m
son = s
m = 8s
m+6 = 9/2 * (s+6)
so
2(8s + 6) = 9(s +6)
16s + 12 = 9s + 54
16s - 9s = 54 - 12
7s = 42
s = 42/7 = 6 years old
so the mother is 8s = 8*6= 48 years old

Answer:
missing side = 50
Step-by-step explanation:
using Pythagoras theorem,
30² + 40² = (missing side)²
900 + 1600 = (missing side)²
(missing side)² = 2500
missing side = √2500
missing side = 50
