Intro to Trigonometry

Front

What is the sine ratio?

Back

sin (A) = opp/hyp

Front

What is the cosine ratio?

Back

cos (A) = adj/hyp

Front

What is the tangent ratio?

Back

tan (A) = opp/adj

Front

What is the ratio of the sine of angle A?

Back

Sin (A) = 28/35

Front

What is the length of the leg adjacent to angle A?

Back

21

Front

What is the length of the hypotenuse in a right triangle with legs 21 and 28?

Back

Hypotenuse = 35

Front

If sin (A) = 28/35, what is the value of opp?

Back

opp = 28

Front

If cos (A) = 4/5, what is the value of adj?

Back

adj = 4

Front

If tan (A) = 1.33, what is the ratio of opp to adj?

Back

opp/adj = 4/3

Front

What is the relationship between sine, cosine, and tangent?

Back

tan (A) = sin (A) / cos (A)
