How to apply the inverse of tangent to find the missing values of your triangle

The video tutorial focuses on finding angle B in a triangle. It begins by identifying the relevant sides: hypotenuse, adjacent, and opposite. The instructor explains the choice of the tangent function for calculation, as it involves the opposite and adjacent sides. The process of calculating angle B using the inverse tangent of the ratio of the opposite to adjacent sides is demonstrated. The tutorial concludes with guidance on rounding the result appropriately.

What is the first step in solving for angle B in a right triangle?

• Find the hypotenuse

• Determine the perimeter

• Identify angle X

• Calculate the area

Which trigonometric function is used when the hypotenuse is not involved?

• Sine

• Secant

• Cosine

• Tangent

What is the formula for the tangent of an angle in a right triangle?

• Adjacent over Hypotenuse

• Opposite over Hypotenuse

• Opposite over Adjacent

• Hypotenuse over Opposite

How do you find angle B using the tangent function?

• Use sine inverse of opposite over hypotenuse

• Use cosine inverse of adjacent over hypotenuse

• Use tangent inverse of opposite over adjacent

• Use secant inverse of hypotenuse over adjacent

When rounding the calculated angle, what is a common practice?

• Round to the nearest whole number

• Round to the nearest tenth

• Round to the nearest hundredth

• Do not round
