Let's solve for the other leg length
a^2 + 21^2 = 42^2
a^2 + 441 = 1764
subtract 441 from both sides
a^2 = 1323
take the square root of both sides
a = sqrt.(1323)
a = 21 sqrt.(3)
The correct answer is C.) The length of the remaining leg is 21 sqrt.(3).
Hope this helps
You could find the interest paid by simply realizing that:
502.33(12)30-150000=total interest paid
i=502.33(12)30-150000
i=$30838.80
4 divided by 6 times 5 equals 3.333
88/100 = 44/50 = 22/25 = 1 3/25
