The hypotenuse of a triangle is 12 the side oppsite to the angle 40 is 5 what is the cos of that angle.
sin= 5/12
The hypotenuse of a triangle is 10 the side adjacent to the angle 30 is 2 what is the cos of that angle.
cos= 2/10
The adjacent side of a triangle with the angle 20 is 7 the side opposite to 20 is 3 what is the tan of that angle?
tan= 3/7
To convert degrees to radians, multiply by what?
pi/180
What band did Ms. Martell see most recently in concert?
Disturbed
The hypotenuse of a triangle is 15 the side oppsite to the angle 70 is 5 what is the cos of that angle.
sin= 1/3
The hypotenuse of a triangle is 18 the side adjacent to the angle 40 is 3 what is the cos of that angle?
cos= 1/6
The adjacent side of a triangle with the angle 40 is 28 the side opposite of 40 is 4 what is the tan of that angle?
Convert the radian degree pi/6 to degrees
30
pi/6 x 180/pi = 30

What is the reciprocal of the ratio sin?
Cosecant (csc)
csc= hypotenuse/opposite
What is the reciprocal of the ratio cos?
secant (sec)
sec= hypotenuse/adjacent
What is the reciprocal of the ratio tan?
Cotangent (cot)
cot= adjacent/opposite
Convert the degree 80o to radians
80o x pi/180 = 4pi/9

36
The opposite side has length 6, the side adjacent has length of 12, and the hypotenuse has length 18. What is the cosecant?
csc = 18/6 = 3
The opposite side has length 5, the adjacent side has length of 15, and the hypotenuse has length of 25. What is the secant?
sec = 25/15 = 5/3
The opposite has side length 4, the adjacent side has length 8, and the hypotenuse has length 20. What is the cotangent?
cot = 8/4 = 2
