Answer :
you would use the pythagorean theorem to solve this equation: a^2 + b^2 = c^2
12^2 + b^2 = 20^2
b^2 = 16
x = 16
12^2 + b^2 = 20^2
b^2 = 16
x = 16
Answer:
16
Step-by-step explanation:
here's your solution
=> The given traingle is Right angle traingle
so, hypotenuse^2 = Base^2 + Height^2
=> x^2+12^2 = 20^2
=> x^2 + 144 = 400
=> x^2 = 400 - 144
=> x^2 = 256
=> x = √256
=> x = 16
hope it helps
