Front

What is the ratio for Sine?

Back

Opposite Leg / Hypotenuse.

Front

What is the ratio for Cosine?

Back

Adjacent Leg / Hypotenuse.

Front

If a ramp is 5 feet high and 8 feet away from a building, what is the angle of elevation?

Back

Use the tangent ratio: tan(angle) = opposite/adjacent.

Front

How do you calculate the angle of elevation using a right triangle?

Back

Use the inverse tangent function: angle = arctan(opposite/adjacent).

Front

What is the relationship between angles of elevation and depression?

Back

They are equal when measured from the same horizontal line.

Front

In a right triangle, if the opposite side is 6 and the adjacent side is 8, what is the angle of elevation?

Back

Use arctan(6/8) to find the angle.

Front

What is the purpose of using angles of elevation and depression in real life?

Back

They are used in fields like architecture, aviation, and navigation.
