Using trig functions to find the values of a triangle

The video tutorial covers solving a triangle problem by finding missing angles and sides using geometry and trigonometry. It explains the sum of angles in a triangle, the use of tangent, sine, and cosine functions, and different methods to calculate the hypotenuse, including the Pythagorean theorem. The tutorial emphasizes that multiple approaches can yield the same result.

What is the sum of all angles in a triangle?

• 90 degrees

• 180 degrees

• 270 degrees

• 360 degrees

Which trigonometric function is used when you have opposite and adjacent sides?

• Secant

• Cosine

• Sine

• Tangent

What is the value of angle A if angle B is 71 degrees in a right triangle?

• 19 degrees

• 45 degrees

• 71 degrees

• 90 degrees

If angle A is 19 degrees, what is the tangent of angle A?

• 19/71

• 71/19

• 24/8

• 8/24

Why is it easier to solve for a side when it is in the numerator?

• It uses a different formula

• It doesn't matter

• It is more accurate

• It requires fewer steps

Which theorem can be used to find the hypotenuse of a right triangle?

• Pythagorean theorem

• Law of Sines

• Law of Cosines

• Triangle Sum Theorem

Which trigonometric function can be used to find the hypotenuse if the opposite side is known?

• Cosine

• Cotangent

• Sine

• Tangent
