12/2 Warm-Up (Honors)

Front

What is the process to find the value of x in an equation?

Back

To find the value of x, isolate x on one side of the equation using algebraic operations such as addition, subtraction, multiplication, or division.

Front

What is the tangent ratio in a right triangle?

Back

The tangent ratio is defined as the ratio of the length of the opposite side to the length of the adjacent side. It is expressed as tan(θ) = opposite/adjacent.

Front

What type of triangle is used with trigonometric ratios?

Back

Trigonometric ratios are specifically used with right triangles.

Front

How do you find the measure of a missing angle in a triangle?

Back

To find a missing angle, use the fact that the sum of angles in a triangle is always 180 degrees. Subtract the sum of the known angles from 180.

Front

What is the sine ratio in a right triangle?

Back

The sine ratio is defined as the ratio of the length of the opposite side to the length of the hypotenuse. It is expressed as sin(θ) = opposite/hypotenuse.

Front

What is the cosine ratio in a right triangle?

Back

The cosine ratio is defined as the ratio of the length of the adjacent side to the length of the hypotenuse. It is expressed as cos(θ) = adjacent/hypotenuse.

Front

How do you round a number to the nearest tenth?

Back

To round a number to the nearest tenth, look at the hundredths place. If it is 5 or greater, round up the tenths place by one. If it is less than 5, keep the tenths place the same.

Front

What is the formula for finding the length of a side in a right triangle using trigonometric ratios?

Back

The length of a side can be found using the ratios: opposite = hypotenuse * sin(θ), adjacent = hypotenuse * cos(θ), or opposite = adjacent * tan(θ).

Front

What is the relationship between the sides and angles in a right triangle?

Back

In a right triangle, the angles determine the ratios of the lengths of the sides, which can be expressed using sine, cosine, and tangent.

Front

What is the definition of a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.
