The trapezoid in the figure has equal nonparaellel sides. the upper base is 6 the lower base is 16 and the diagonal is 12. what is the altitude of the trapezoid

4.8

Explanation:

We have assume a  right triangle to be formed from the given description  so for the altitude we can use the Pythagoras theorem.

a²+b²=c²    (where a and b are the side lengths and c is the hypotenuse)

Putting the values that we have.

11²+b²=12²

simplify this,

121+b²=144

subtract 121 from both sides

b²=23

To solve for the missing side/altitude we just need to find the square root of 23

b=√23

It is approximately 4.8

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
