An elephant weighs 5000 kg. It eats 150 kg each day. What percent of its own weight does an elephant eat each day?

The length of the opposite side is the same as the length of the hypotenuse (they are the same side in this case), the ratio is:

sin(90 degrees) = 1 / 1 = 1

Thus, sin(90 degrees) equals 1.

In trigonometry, the sine function (abbreviated as sin) is defined based on the angles of a right-angled triangle.

Specifically, for a given angle θ in a right-angled triangle, the sine of θ is defined as the ratio of the length of the side opposite θ to the length of the hypotenuse (the longest side of the triangle, which is always opposite the right angle).

In a standard coordinate system, consider a right-angled triangle where one of the angles is 90 degrees (a right angle).

This angle is often denoted as π/2 radians in radians or 90 degrees in degrees.

In this triangle, the side opposite the angle θ (the side opposite the right angle) is the vertical side, and the hypotenuse is the longest side.

For a right-angled triangle with a 90-degree angle, the sine of θ is defined as:

sin(90 degrees) = length of opposite side / length of hypotenuse

Since the length of the opposite side is the same as the length of the hypotenuse (they are the same side in this case), the ratio is:

sin(90 degrees) = 1 / 1 = 1

Thus, sin(90 degrees) equals 1.

In radians, sin(π/2 radians) is also equal to 1 since it is the same angle as 90 degrees but measured in radians.

There are 4 quarts in one gallon:

1 gal = 4 qt

Then, we want to find the number of quarts in 19 gallons. We can write a proportion:

1/4 = 19/x

Cross multiply:

x = 76 quarts.

There are 76 quarts in 19 gallons.

76 quarts in 19 gallons

Step-by-step explanation:

10/4=2.5

Answer:

9 sq units

Step-by-step explanation:

The square would reach about 3 units so you do 3 times 3 equal 9
