Hunter-Best [27]

Answer:

127.3 ft

Step-by-step explanation:

A baseball diamond is constructed in a square shape.

The sides are 90 ft each

If a catcher throws a baseball to the shortstop who is half-way between second and third bases, the distance between the third base and the short stop = 1/2(90)

= 45 ft

length of the throw is found using Pythagoras theorem.

Hypothenus ^2 = opposite ^2 + adjacent ^2

= 90^2 + 45^2

Hypothenus = √8100 + 2025

=√10125

= 100.62 ft (approximately)

PLEASE HELP ME ASAP!!! The diagonal of Andres rectangular TV screen is 39 in. The width of his TV screen is 34 inches. which mea
Y_Kistochka [10]
You can use the Pythagorean theorem to answer this. The diagonal is the hypotenuse of the right triangle that is formed. So, your equation will look like (h is height):
34^2+h^2 = 39^2

We have to solve for h:
h^2 = 39^2-34^2
h =  \sqrt{39^2-34^2}

You can plug it into a calculator, and you get approximately 19.105. The answer closest to that is B. So, that's your answer! Hope it helps. If anything doesn't make sense, hmu!
