Answer:

z = 66

Step-by-step explanation:

RS = z

QT = z - 33

Based on the midsegment theorem, QT = ½(RS)

Plug in the values

z - 33 = ½(z)

Multiply both sides by 2

2(z - 33) = z

2z - 66 = z

Add 66 to both sides

2z = z + 66

Subtract z from both sides

2z - z = 66

z = 66

Can somebody PLEASE HELP ME??? trying to correct answers and i have no clue how to do this.

Answer:

613 inches

Step-by-step explanation:

Area right triangle = 10,710

Formula for area of a triangle = 1/2(base x height)

We need to find the base because height and area is given

Reverse divide by 2 by doing multiply by 2

10,710 x 2 = 21420

Revers multiply by 612 by dividing by 612

21420 / 612 = 35

Base = 35

Formula for hypotenuse = a² + b² = c²

In this case a = 35, b = 612, and c = hypotenuse

35² + 612² = c²

1225 + 374544 = c²

375769 = c²

Square root of 375769 = 613

Hypotenuse = 613

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!
