Which side lengths given below can form a right triangle
12,13,17
3.2,5.6,6.4
14,20,24
10,24,26

If a triangle is a right triangle
and if the legs measure a and b and the hyptonuse measures c,then

a²+b²=c²

test them

12,13,17
hypothuse is longest side so 17=c
12²+13²=17²?
144+169=289?
nope

3.2,5.6, 6.4
6.4=c
3.2²+5.6²=6.4²?
10.24+31.36=40.96?
nope

14,20,24
24 is longest so 24=c
14²+20²=24²?
196+400=576?
nope

10,24,26
26 is hyptohuse
10²+24²=26²?
100+576=676?
true

answer is 10,24,26

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
