Question

How do I do this!! I’m so confused

Answer 1

So each example is still in the ratio of the triple on the left.
**note: the largest factor will alway be the hypotenuse

a.1. 15, 20, ? in a 3, 4, 5 ratio
15/5 = 3
20/5 = 4
x/5 = 5
x = 5×5 = 25

b.1. ?, 24, 26 in a 5, 12, 13 ratio
26/2 = 13
24/2 = 12
x/2 = 5
x = 2×5 = 10

c.1. 70, 240, ? in a 7, 24, 25 ratio
70/10 = 7
240/10 = 24
x/10 = 25
x = 10×25 = 250

d.1. 24, 45, ? in an 8, 15, 17 ratio
24/3 = 8
45/3 = 15
x/3 = 17
x = 3×17 = 51
