Solving a Right Triangle Problem: Finding the Height of a Gymnastics Mat

In this article, we will explore a problem involving a right triangle formed by a gymnastics mat. The mat extends 5 feet across the floor and forms a right triangle with angles measuring $$60^{\circ}$$ and $$30^{\circ}$$. Our goal is to find the height of the mat off the ground. To solve this problem, we will use trigonometric ratios and the properties of right triangles.

The problem involves a right triangle with angles measuring $$60^{\circ}$$ and $$30^{\circ}$$. We are given that the mat extends 5 feet across the floor, which corresponds to the base of the right triangle. Our objective is to find the height of the mat off the ground, which is the opposite side of the $$30^{\circ}$$ angle.

To solve this problem, we can use the trigonometric ratio for the sine function, which is defined as:

\sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}}

In this case, we want to find the height of the mat, which is the opposite side of the $$30^{\circ}$$ angle. We can use the sine function to relate the height to the base of the triangle, which is 5 feet.

Using the sine function, we can write:

\sin(30^{\circ}) = \frac{\text{height}}{5}

We know that the sine of $$30^{\circ}$$ is equal to $$\frac{1}{2}$$. Therefore, we can substitute this value into the equation:

\frac{1}{2} = \frac{\text{height}}{5}

To solve for the height, we can multiply both sides of the equation by 5:

\text{height} = \frac{1}{2} \times 5

\text{height} = \frac{5}{2}

Therefore, the height of the mat off the ground is $$\frac{5}{2}$$ feet.

In this article, we used trigonometric ratios to solve a problem involving a right triangle formed by a gymnastics mat. We found that the height of the mat off the ground is $$\frac{5}{2}$$ feet. This problem demonstrates the importance of understanding trigonometric ratios and how they can be applied to solve real-world problems.

Frequently Asked Questions: Solving Right Triangle Problems

In our previous article, we explored a problem involving a right triangle formed by a gymnastics mat. We used trigonometric ratios to find the height of the mat off the ground. In this article, we will answer some frequently asked questions related to solving right triangle problems.

Q: What is a right triangle?

A: A right triangle is a triangle with one angle measuring 90 degrees. The side opposite the 90-degree angle is called the hypotenuse, and the other two sides are called the legs.

Q: What are the different types of right triangles?

A: There are several types of right triangles, including:

30-60-90 triangle: A right triangle with angles measuring 30, 60, and 90 degrees.
45-45-90 triangle: A right triangle with angles measuring 45, 45, and 90 degrees.
Isosceles right triangle: A right triangle with two sides of equal length.

Q: How do I use trigonometric ratios to solve right triangle problems?

A: To solve right triangle problems using trigonometric ratios, you need to identify the type of triangle and the given information. Then, you can use the sine, cosine, or tangent function to relate the given information to the unknown side.

Q: What is the sine function, and how do I use it to solve right triangle problems?

A: The sine function is defined as:

\sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}}

To use the sine function to solve right triangle problems, you need to identify the opposite side and the hypotenuse. Then, you can use the sine function to relate the opposite side to the hypotenuse.

Q: What is the cosine function, and how do I use it to solve right triangle problems?

A: The cosine function is defined as:

\cos(\theta) = \frac{\text{adjacent}}{\text{hypotenuse}}

To use the cosine function to solve right triangle problems, you need to identify the adjacent side and the hypotenuse. Then, you can use the cosine function to relate the adjacent side to the hypotenuse.

Q: What is the tangent function, and how do I use it to solve right triangle problems?

A: The tangent function is defined as:

\tan(\theta) = \frac{\text{opposite}}{\text{adjacent}}

To use the tangent function to solve right triangle problems, you need to identify the opposite side and the adjacent side. Then, you can use the tangent function to relate the opposite side to the adjacent side.

Q: How do I choose which trigonometric ratio to use to solve a right triangle problem?

A: To choose which trigonometric ratio to use, you need to identify the type of triangle and the given information. Then, you can use the sine, cosine, or tangent function that is most relevant to the problem.

Q: What are some common mistakes to avoid when solving right triangle problems?

A: Some common mistakes to avoid when solving right triangle problems include:

Not identifying the type of triangle: Make sure to identify the type of triangle and the given information before using trigonometric ratios.
Not using the correct trigonometric ratio: Make sure to use the correct trigonometric ratio for the problem.
Not checking units: Make sure to check units to ensure that the answer is in the correct units.
