Front

If a kite is caught at the top of a tree, how can you estimate the height of the tree using trigonometry?

Back

Use the sine ratio to find the height based on the angle and distance.

Front

Solve for x: If sin(x) = 0.99, what is x rounded to the nearest tenth?

Back

9.9

Front

Find the measurement of the missing side indicated in a right triangle if one side is 2.05 and the angle is known.

Back

Use trigonometric ratios to find the missing side.

Front

What does 'Soh Cah Toa' stand for?

Back

Soh: Sin = Opp/Hyp, Cah: Cos = Adj/Hyp, Toa: Tan = Opp/Adj

Front

In a right triangle, if the opposite side is 4 and the hypotenuse is 5, what is sin(X)?

Back

sin(X) = Opp/Hyp = 4/5 = 0.8

Front

What is the cosine ratio?

Back

Cosine (cos) = Adjacent side / Hypotenuse

Front

If tan(X) = 1, what is the value of X?

Back

X = 45 degrees

Front

How do you find the height of an object using trigonometry?

Back

Use the formula: Height = Distance * tan(angle)
