Answer:
Step-by-step explanation:
First note that the triangles shown are isosceles triangles due to equality of two of their sides which is radius. So their baseline angles are equal
Since their middle angle are equal too, so their 3 angles are the same. It menas both triangles are similar.
However, we know two of three sides are equal, but the third should be also because of their similarity.
y+4 = 2y - 3
2y - y = 4 - 3
y = 4+3
y = 7
Therefore,
2y-3 = 2.7-3 = 14-3 = 11
Answer is 11 centimeters
The Answer will be 'A'. Hope this helps!! :D
Answer:
The standard deviation is 1.5 inches.
Step-by-step explanation:
For a normal curve, we have that the area between the mean and the mean plus two times the standard deviation is something around 47.5%
Then the area between the mean minus two times the standard deviation and the mean plus two times the standard deviation is equal to the 95%.
the mean is 66
if the standard deviation is x, we have that:
66 + 2*x = 69
66 - 2*x = 63
then we can find that:
2*x = 66 - 63 = 3
x = 3/2 = 1.5
The standard deviation is 1.5 inches.
The solution to the problem is as follows:
Tan(sqrt(3)/3) * sqrt(3)/sqrt(3) = 1/sqrt (3)
therefore θ = 3 0 degrees = <span>Π/6

The only one that wouldn’t change the y-value is a reflection across the y-axis.
