Introduction to Right Triangle Trigonometry

Is tanA the reciprocal of cotA

• NO

• YES

• 0

• 1

In a right angled triangle the side opposite to right angle is called

• Base

• Perpendicular

• Hypotenuse

• None of the above

 FInd tanX

• 32/40

• 40/24

• 32/24

• 24/32

Set up the problem.

• sin(47) = x/28

• cos(47) = x/28

• tan(47) = x/28

• cos(47) = 28/x

Find the value of sin Z.

• 20/21

• 21/29

• 21/20

• 20/29

cos B = ? Remember: Cosine ratio is adjacent/hypotenuse

• 12/13

• 12/5

• 5/13

• 5/12

In triangle ABC, AC = 5 cm, AB =13 cm ,then cosec A is

• 5/12

• 13/5

• 5/13

• 13/12

Find the value of each trigonometric ratio.

In triangle ABC, BC =3 cm, AB =5 cm ,then tan A is 

• 3/5

• 4/5

• 3/4

• 4/3
