Trig ratios

Front

What is the definition of sine in a right triangle?

Back

Sine (sin) is the ratio of the length of the opposite side to the length of the hypotenuse.

Front

What is the sine of 33 degrees in the context of a right triangle?

Back

sin(33°) = opposite/hypotenuse.

Front

If sin(33°) = x/14, how do you solve for x?

Back

Multiply both sides by 14: x = 14 * sin(33°).

Front

What is the approximate value of sin(33°) when calculated?

Back

Approximately 0.5446.

Front

If x = 14 * sin(33°), what is the value of x rounded to the nearest tenth?

Back

x ≈ 7.6.

Front

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

Back

sin(X) = Opposite side / Hypotenuse.

Front

What is the relationship between sine and cosine in a right triangle?

Back

sin(X) = cos(90° - X).

Front

What is the sine ratio for an angle of 90 degrees?

Back

sin(90°) = 1.

Front

What is the sine ratio for an angle of 0 degrees?

Back

sin(0°) = 0.

Front

How do you find the hypotenuse if you know the opposite side and the sine of the angle?

Back

Hypotenuse = Opposite side / sin(angle).
