Finding Missing Angles in Right Triangle Trigonometry

The video tutorial covers solving right triangles, focusing on finding missing angles using inverse trigonometric functions. It explains how to use a calculator to find angles with inverse sine, cosine, and tangent functions. The tutorial includes example problems and demonstrates solving a right triangle completely by finding all sides and angles.

What trigonometric ratio is used when the opposite side and hypotenuse are known?

• Sine

• Tangent

• Cotangent

• Cosine

What does the inverse trigonometric function accomplish?

• Calculates hypotenuse length

• Solves quadratic equations

• Finds missing angles

• Determines side ratios

What is the Greek letter commonly used to represent angles in trigonometry?

• Alpha

• Theta

• Beta

• Gamma

How do you use a calculator to find an angle using the inverse tangent function?

• Use the 'cosine' button

• Directly input the angle degrees

• Calculate the ratio then use 'second tangent'

• Type the ratio and press 'inverse'

What is the correct way to round angle measures for final answers?

• To the nearest whole number

• To the nearest tenth

• To the nearest hundredth

• No rounding necessary

When given the opposite and adjacent sides, which function is used to find the angle?

• Sine

• Cotangent

• Cosine

• Tangent

Which trigonometric function is used with the adjacent side and hypotenuse?

• Sine

• Secant

• Cosine

• Cosecant

How do you find the missing side in a right triangle?

• Using any trigonometric function

• Using the Pythagorean theorem

• Summing the known sides

• Subtracting the known sides

What is the sum of the angles in any triangle?

• 270 degrees

• 360 degrees

• 180 degrees
