In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the legs.

C squared= a squared + b squared

G

10^2+b^2=25^2

solve for b

solve for b

c = length of ladder = 25 ft

a = distance of ladder base from the house = 10 ft

b = height of roof

b = 15? Where did you get that? SHOW YOUR WORK!!!

It isn't magic. No one knows what is in your head. You must tell us.

G

no b=the square root of 525

G

25^2=10^2+b^2

625=100+b^2

525=b^2

625=100+b^2

525=b^2
