Answer:
4 and 12
Step-by-step explanation:
a = young
b = old
b = 3a, a+b =2a+8 => a = 4, b = 12
-- Since the acute angles are equal, the legs are equal lengths.
-- Since the triangle is a right triangle, (leg)² + (leg)² = (22)² .
2 · (leg)² = (22)²
√2 · (leg) = 22
Leg = (22) / √2
Leg = (22) · √2 / 2
Leg = 11 · √2 (E)
Volume = Length x Width x Height
270 = 15 x 9 x height
270 = 135 x height
height = 270 ÷ 135
height = 2m
