Answer:
x=12
Explanation:
To solve this question, we need to use the equation a^2+b^2=c^2.
A and B are the sides of the right triangle that are perpendicular to each other and C is the diagonal side. So, in this case, a=16, b=x and c=20.
1) plug values into the equation
a^2+b^2=c^2
16^2+x^2=20^2
2) expand the squares
256+x^2=400
3) Subtract both sides by 256
x^2=400-256
x^2=144
4)Square root both sides
x=12
