BE is the diameter of circle A. What's the measure of ∠BCE? Diagram below

Question options:

1)

88°

2)

90°

3)

180°

4)

93°

2. 90°

Step-by-step explanation:

According to the central angle theorem, an inscribed angle is always twice the measure of the central angle.

Thus, the central angle A, is 180°, because it is a straight angle.

Therefore, the measure of the inscribed angle, <BCE would be ½ of 180°.

m<BCE = 90°

just keep asking questions until you have a better understanding.

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
