Answer:
Step-by-step explanation:
Dilation
Answer:
2 - sqrt(3)
Step-by-step explanation:
Split pi/12 into two angles where the values of the six trigonometric functions are known.
tan (pi/4 - pi/6)
Apply the difference of angles identity

tan(pi/4) = 1 , tan(pi/6) = (sqroot3)/3
Plug in and Simplify



Need to multiply this by 
Expand and simplify numerator: 
Expand and simplify denominator: 
Cancel the common factor: 
Well there is no following but I can tell you that the probability of getting tails is 48/100 which they probably want simplified which jusst means divide both numerator and denominator(top and bottom numbers) by Z (whatever number works) untill it can't be a whole number anymore(a number without a decimal number), simply put, divide top and bottom numbers by the GCM(Greatest Common Multiple) which in this case is 4. 48/4=12, 100/4=25 48/100=12/25 you can't simplify that any more so the answer is 12/25
The Answer Is 12/25 or 48%
Hope This Helps.
Answer:

Step-by-step explanation:
Look at the picture.
ΔADC and ΔACB are similar. Therefore the corresponding sides are in proportion:

We have

Substitute:
<em>cross multiply</em>
