Learn how to find the missing side of a triangle using the law of sines

The video tutorial explains how to solve for a missing side in a triangle using the law of sines. It covers setting up a proportion with a given side and angle, solving the proportion through cross multiplication, and using a calculator to find and round the final answer.

What is the first step in solving for a missing side using the Law of Sines?

• Directly calculate the missing side using a calculator.

• Guess the length of the missing side.

• Identify a side and its opposite angle to create a ratio.

• Use the Pythagorean theorem.

How do you set up the proportion for solving a missing side in a triangle?

• Use any two angles in the triangle.

• Use the known side and its opposite angle, and another angle in the triangle.

• Use the known side and any angle in the triangle.

• Use the known side and the angle adjacent to it.

What is the purpose of multiplying by the sine of 24 degrees in the calculation?

• To check if the calculator is in degree mode.

• To find the cosine of the angle.

• To cancel out the division by sine of 24 degrees.

• To convert the angle to radians.

What should you ensure before performing calculations on a calculator for trigonometric problems?

• The calculator is in radian mode.

• The calculator is in degree mode.

• The calculator is set to scientific notation.

• The calculator is in fraction mode.

How should the final answer be rounded in this problem?

• To the nearest hundredth.

• To the nearest tenth.

• To the nearest whole number.

• To the nearest thousandth.
