What is the measure of the indicated angle if the options are 9.4, 55.2, 20.15, 19.4?

Back

The measure of the indicated angle is 55.2.

Front

A yacht is anchored 90 feet offshore from the base of a lighthouse. If the angle of elevation from the boat to the top of the lighthouse is 26 degrees, what is the height of the lighthouse?

Back

The height of the lighthouse is approximately 45 feet.

Front

Do the sides 15, 30, and 34 make a right triangle?

Front

Solve for the missing angle if the options are 50, 0.053, 36.9, 95.

Back

The missing angle is 36.9.

Front

Which Law would you use to solve a triangle if given two angles and one side?

Back

You would use the Law of Sines.

Front

What is the Law of Sines?

Back

The Law of Sines states that the ratio of a side length to the sine of its opposite angle is constant for all three sides of a triangle.

Front

What is the Law of Cosines?

Back

The Law of Cosines relates the lengths of the sides of a triangle to the cosine of one of its angles, useful for finding a side or angle in non-right triangles.

Front

How do you determine if a triangle is a right triangle using the Pythagorean theorem?

Back

A triangle is a right triangle if a² + b² = c², where c is the length of the hypotenuse.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: Area = 1/2 * base * height.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.
