Answer:
H^2 = P^2+ B^2
10^2 = 3x^2 +4x^2
100 = 9x^2 + 16x^2
100 = 25x^2
100 ÷ 25 = x^2
4 = x^2
x= 2
Length of longer arm is 4x = 4×2=8
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
ratios of legs = 3x and 4x
Pythagorean theorum:
A^2+B^2=C^2
3x^2+4x^2=10^2
9x^2+16x^2=100
25x^2=100 --> divide by 25
x^2=4 --> x=2
length of longer leg is 4x = 4 x 2 = 8
