What is the length of the unknown leg in the right triangle? this is urgent now!

Since there is a right angle, we can use the pythagorean theorem. Here, 25M represents the hypotenuse, one of the legs is 20m. We can solve backwards to find the

a^2+b^2=c^2

a=20

c=25

b=b

20^2+b^2=25^2

400+b^2=625

b^2=225

b=+/-15

But since geometry ONLY follows real life scenarios, the only answers can be of positive infinity. That would mean +15. Your answer is 15, or D.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
