For this case we can use the following trigonometric relationship:
tan (theta) = y / x
Substituting values we have:
tan (theta) = (4/5) / (3/5)
Rewriting we have:
tan (theta) = 4/3
Clearing theta:
theta = Atan (4/3)
theta = 53.13 degrees
Answer:
the approximate value of teta is:
theta = 53.13 degrees
Answer:
B. The probability is 54.54% and the event is likely
Step-by-step explanation:
12/22=.5454*100=54.54%
I believe that the answer should be terms
Answer:
10 inches by 4 inches
Step-by-step explanation:
Area of envelope, A = 40 in²
Perimeter of envelope, P = 28 in
Area = Length * width, L*W
Perimeter = 2(L + W)
40 = LW - - - (1)
28 = 2(L+W)
28/2 = L+W
14 = L+W - - - (2)
Solving like a quadratic equation ;
We need two numbers whose sum gives 14 and product gives 40
The numbers are 10 and 4
(10*4) = 40 and (10+4) = 14
