If sin 21 = cos (5x+9) what is the value of x

Mathematics
1 answer:
n200080 [17]4 years ago
4 0

sin x = cos 54 = sin (90-54) = sin 46

Hence x = 46 deg

Same technique. Sin 21 = cos (5x+9) = sin (90-5x-9)

81-5x = 21

Or 5x = 60

Or x = 12 deg

hope it helps

A pharmacist put 4.536 ounces of vitamin pills into bottles. She put .042 ounce of vitamin pills into each bottle.
Rama09 [41]

Answer:

108 bottles

Step-by-step explanation:

the total is 4.536 oz of vitamin pills

each bottle can accomodate 0.042 oz of vitamin pills

to know the quantity of each bottle

we calculate

0.042 oz of vitamin pills  = 1 bottle

4.536 oz of vitamin pills = (4.536 x 1)/0.042=108

so therefore 4.536 oz of vitamin pills will accommodate 108 bottles
