A triangular pyramid is formed from three right triangles as shown below.

Bess [88]

Answer:

FH = 108

Step-by-step explanation:

The given figure requires we use the Pythagorean theorem to write two relations involving right triangle side lengths. The Pythagorean theorem tells us the square of the hypotenuse is the sum of the squares of the other two sides.

__

<h3>Triangle EGH:</h3>

EG² = GH² +HE²

GH² = EG² -HE² = 53² -28² = 2025 . . . . . solve for GH², use given values

<h3>Triangle FGH:</h3>

FG² = GH² +FH²

FH² = FG² -GH² = 117² -2025 = 11664 . . . . solve for FH², use known values

FH = √11664 = 108 . . . . . take the square root

The length FH is 108.

Over the summer, Jackie played video games 3 hours per day. When school began in the fall, she only allowed to play video games

erik [133]

So to find this we divide 3 by 1/2 and get 6. So, she is now only at 1/6 of her original time.1/6 is equal to .1666, and to the nearest percent that would be 17%. hope this helps and its not too late!
