Question

Find the the length of the unknown side round to the nearest tenth

Answer 1

Answer:

The length of the missing side b would be 16m

Step-by-step explanation:

first you would use the formula a2+b2=c2

12^2+b2=20^2

-take 12*12 and 20*20

144+b2=400

-subtract 144 from 400 in order to get b2 alone

b2=256

-take the square root of b and 256

b=16
