Front

What is the sine of 58 degrees?

Back

0.5299 (approximately)

Front

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

Back

sin(θ) = opposite/hypotenuse

Front

What is the relationship between the sides of a triangle with angles A, B, and C?

Back

a/sin(A) = b/sin(B) = c/sin(C) (Law of Sines)

Front

If angle A is 31 degrees, side b is 18m, and side c is 22m, how can you find side a?

Back

Use the Law of Sines: a = (b * sin(A))/sin(B) where B is the angle opposite side b.

Front

What is the formula for finding the area of a triangle given two sides and the included angle?

Back

Area = 0.5 * a * b * sin(C) where a and b are the sides and C is the included angle.

Front

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

Back

cos(θ) = adjacent/hypotenuse

Front

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

Back

tan(θ) = opposite/adjacent
