Hi hi hi could someone please help m If the length of a base of right triangle DEF is 8 units and the hypotenuse of DEF 8√5 units, what is the length of the other base?

The other base = 16 units

Step-by-step explanation:

Use the Pythagorean Theorem

a² + b² = c²

a² = c² - b²

a² - c² = -b²

-a² + c² = b

-8² + (8√5)² =b²

Then solve for b

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to
