Question

What is the missing leg length

Answer 1

36

Explanation:

a2+b2=c2

a2+27^2=45^2

a2+729=2025

a2=1296

then square root that number to get

a=36

Answer 2

36 km

Explanation:

This is a right triangle so we can use Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

27^2+ b^2 = 45^2

729+b^2 =2025

Subtract 729 from each side

729-729+b^2 =2025-729

b^2 =1296

Take the square root of each side

b =sqrt(1296)

b=36
