Answer:
28.07° ; 70.53° ; 53.13° ; 36.87°
Step-by-step explanation:
Using PYTHAGORAS RULE :
IMAGE 1:
value of cos α equals :
cos α = Adjacent / Hypotenus
cos α = 15 / 17
cos α = 0.88235
α = cos^-1 (0.88235)
α = 28.07°
IMAGE 2:
sin β = Opposite / Hypotenus
sin β = 14√2 / 21
sin β = 0.9428
β = sin^-1(0.9428)
β = 70.53°
IMAGE 3:
From trigonometry :
cot = 1 / tan
Tan = Opposite / Adjacent
Therefore, Cot = Adjacent / Opposite
cot γ = 3/4
cot γ = 0.75
γ = cot^-1 (0.75)
γ = 53.13°
IMAGE 4:
tan α = Opposite / Adjacent
tan α = 15 / 20
tan α = 0.75
α = tan^-1 (0.75)
α = 36.87°
Answer:
Just a cheerful teen willing to help,
wishing you a splendiferous day.
Step-by-step explanation:
In order to find the total number of boxes, workout 100% of the boxes of cereal.
100% is 20% in 5 places,
Therefore 17×5 equals 85.
There are 85 boxes of cereal in total...
Answer: 3 11/20
explanation: change 3 3/4 to a mixed number which is 15/4 then get a common denominator which is 75/20 - 4/20 then subtract and get 71/20 and then change to a mixed number and simplify to get 3 11/20
The numbers are {10, 11, 12, ... , 23, 24}.
Can we divide 11 by 1? yes. can we divide the other digit of 11 by 1? yes. Thus, 11 satisfies the criterion "they are divisible by each of their digits."
What about 12: is 12 divisible by 1? YES. Is 12 divisible by 2? YES.
And so on.
Answer:
2.85
Step-by-step explanation:
You divide 14.25 by 10 then multiply that by 2
equation: (14.25 divided by 10)2
