Math 2 Exam Review Day 1

Front

What is the formula to find the height of a ladder leaning against a wall given the angle and the length of the ladder?

Back

Height = Length * sin(Angle)

Front

If a ladder makes an angle of 68° with the ground and is 16 feet long, how high does it reach?

Back

Height = 16 * sin(68°) ≈ 14.8 feet

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180°.

Front

How do you determine if two triangles are similar?

Back

Two triangles are similar if their corresponding angles are equal or their sides are in proportion.

Front

What is the probability of an event?

Back

Probability = (Number of favorable outcomes) / (Total number of outcomes).

Front

If you flip a coin and roll a die, how many total outcomes are there?

Back

Total outcomes = 2 (coin) * 6 (die) = 12.

Front

What is the probability of drawing a yellow gummy bear from a bag containing 4 red, 5 green, and 3 yellow bears?

Back

Probability of yellow = 3/12 = 1/4.

Front

What is the probability of drawing a yellow gummy bear followed by a red gummy bear without replacement?

Back

Probability = (3/12) * (4/11) = 1/11.

Front

What is the sine function in relation to a right triangle?

Back

Sine = Opposite side / Hypotenuse.

Front

What is the cosine function in relation to a right triangle?

Back

Cosine = Adjacent side / Hypotenuse.
