How to use tangent to find the missing leg of a triangle

The video tutorial explains how to find a missing side length in a triangle when traditional methods like the Pythagorean theorem and special triangles are not applicable. It introduces the use of trigonometric functions, specifically the tangent function, to solve the problem. The tutorial guides through identifying the given and required sides, applying the tangent function, and solving the equation to find the missing side length using a scientific calculator.

What is the main challenge in finding the missing side of the triangle as discussed in the first section?

• The triangle is a special right triangle.

• Traditional methods like the Pythagorean theorem cannot be used.

• The triangle has no known angles.

• The triangle is not a right triangle.

Which trigonometric function is identified as suitable for solving the problem in the second section?

• Sine

• Cosine

• Secant

• Tangent

In the context of the problem, which sides of the triangle are relevant for using the tangent function?

• Opposite and hypotenuse

• Adjacent and hypotenuse

• All three sides

• Opposite and adjacent

What is the final step in calculating the missing side length using the tangent function?

• Multiply by the tangent of the angle

• Add the tangent of the angle

• Divide by the tangent of the angle

• Subtract the tangent of the angle

What tool is necessary to complete the calculation of the missing side length?

• A scientific calculator

• A protractor
