Law Of Sines Word Problems Worksheet Pdf With Answers
If you're looking for a way to help your students practice their trigonometric skills, specifically the Law of Sines, then you may want to consider using a worksheet that includes word problems. These types of problems can be particularly challenging for students because they often require them to apply multiple concepts and formulas in order to arrive at a solution.
In this article, we will provide you with a comprehensive Law of Sines word problems worksheet that includes answers in a PDF format. We will also provide you with some tips and tricks for helping your students master this topic.
What is the Law of Sines?
The Law of Sines is a trigonometric formula that relates the sides and angles of a triangle. It states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle.
The formula can be expressed as:
a/sin(A) = b/sin(B) = c/sin(C)
Where:
- a, b, and c are the lengths of the sides of the triangle
- A, B, and C are the angles opposite sides a, b, and c, respectively
The Law of Sines can be used to find the length of a side or the measure of an angle of a triangle when the lengths of the other sides and angles are known.
Why Use Law of Sines Word Problems?
Word problems are a great way to help your students practice their trigonometric skills because they require them to apply multiple concepts and formulas in order to arrive at a solution. This can help them to develop a deeper understanding of the topic and to see how it can be applied in real-world situations.
Additionally, word problems can help to improve students' problem-solving skills and their ability to communicate their thought process and reasoning.

You can download the PDF version of the worksheet here.
- A triangle has sides of lengths 12, 15, and 18. What is the measure of the smallest angle in the triangle?
- A flagpole is leaning because its base is not level. A 20-foot guy wire is attached to the top of the pole and is anchored in the ground 15 feet from the base of the pole. If the angle between the guy wire and the ground is 30 degrees, how tall is the flagpole?
- A ship is sailing towards a lighthouse at a uniform speed. At a certain point, the ship is 2.5 miles away from the lighthouse and the angle of elevation to the top of the lighthouse is 12 degrees. 20 minutes later, the ship is 1.5 miles away from the lighthouse and the angle of elevation to the top of the lighthouse is 15 degrees. How tall is the lighthouse?
- A kite is flying 80 feet above the ground. The length of the string that is attaching the kite to the ground is 100 feet. The angle of elevation from the kite to the ground is 60 degrees. What is the horizontal distance between the kite and the person holding the string?
- An airplane is flying at an altitude of 20,000 feet. The angle of depression to a city on the ground is 32 degrees. How far away is the city?
- A ladder is leaning against a wall. The ladder is 16 feet long and makes a 75-degree angle with the ground. How far up the wall does the ladder reach?
Tips and Tricks for Teaching the Law of Sines
Teaching the Law of Sines can be challenging, but there are some tips and tricks that you can use to help your students master this topic.
- Start with the basics. Make sure that your students have a solid understanding of the definitions of sine, cosine, and tangent before moving on to the Law of Sines.
- Use visual aids. Use drawings and diagrams to help your students visualize the relationships between the sides and angles of a triangle.
- Practice, practice, practice. Give your students plenty of opportunities to practice solving Law of Sines problems. Start with simple problems and gradually increase the difficulty level as they become more comfortable with the formula.
- Encourage collaboration. Encourage your students to work together in pairs or small groups to solve problems. This can help them to learn from each other and to develop their problem-solving and communication skills.
