This is a right triangle (hence the 90° angle), so you'd find the legs (both are the same length of a right triangle) by using Pythagoras Theorem (a2 + b2 = c2) Since you have the hypotenuse (6"), just go backwards. 62 = 36 = a2 + b2. Like I said before the legs are the same length so you can rewrite it as 36 = 2x2, where x = either a or b. Then just solve for x.
She needs 45 kg meat for 2 pets
each pet feed the same, i.e,
one pet eats = 45/2 = 22.5 kg meat
then 4 pet dragons will eat = meat.
Hence, Amara needs 90 kilograms of meat to feed 4 pet dragons each day.
The answer is 20 square meters
<span>In general, the height of a projectile is given by

from initial height
<span>.
The acceleration of gravity </span>
<span> We give it a negative sign in the equation because it pulls down.
Let's apply it to each group.
Group A launches a tennis ball straight up with an initial velocity of 19 meters per second.
We have MKS units, positive (upward) velocity and an initial height of 0.

<span>
Group B launches a tennis ball straight up with an initial velocity of 50 feet per second. Not metric, velocity +50, initial height zero.
</span>
<span>
Group C drops a tennis ball from a height of 19 meters.
MKS, initial height 19, initial velocity zero.

Group D drops a tennis ball from a height of 50 feet.
