36x(squared)-93x-8
This is because you would add the sides and then go to the middle
If m = baseball cards he had yesterday, and today he got rid of 5, the expression is equal to
m - 5 = x.
As an example of what the answer is, replace m with 10.
If he had 10 baseball cards and gave away 5 today, x = 5.
The answer is m - 5 = x.
X= the total questions
x×20%=16. 20%=0.2
so x×0.2=16
solve for x and that is your answer; )
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°
