Questions and Answers

What trigonometric functions might be used to calculate the angles in a triangle?

Only sine and cosine

Sine, cosine, and tangent (correct)

Tangent and cotangent

Secant and cosecant

Which formula would correctly calculate the area of a trapezoid?

Area = base * height

Area = base1 + base2

Area = (perimeter) / 2

Area = (1/2) * (base1 + base2) * height (correct)

What is the circumference of a circle if the diameter is known?

Circumference = diameter imes rac{1}{2}

Circumference = rac{diameter}{ au}

Circumference = diameter imes au (correct)

Circumference = diameter imes rac{ au}{2}
