-845 degree coterminal angle
meriva
Check the picture below.

with negative angles, we go "clockwise", the same direction a clock hands move.

so -360-360-125 = -845.

so as you see in the picture, you go around twice, and then a little bit more, an extra 125°, landing you at -125°, or its positive counterpart, 235°.

Anyone I need help with this problem plss
Nady [450]

Answer:

About 1.23 standard deviation above the mean

Step-by-step explanation:

From what we have here, we need to calculate the difference between the given value and the mean and divide by the standard deviation

That would be through calculating the z score as follows;

z-score = (x - mean)/SD

where x is the given value

z-score = (87-71)/13 = 1.23

Since the score is bigger than the mean, the correct choice here is that the score is about 1.23 standard deviation above the mean

In a rectangle ABCD if AB=4x and DC=7x-9,find the length of AB.(Lengths are in cm).
myrzilka [38]

Answer:

12 cm

Step-by-step explanation:

AB and DC are parallel to each other, so they are the same length. Set their lengths equal to each other and solve for x

4x = 7x - 9

4x - 7x = 7x - 7x -9

-3x = -9

-3x/-3 = -9/-3

x = 3

Now solve for AB.

AB = 4x

AB = 4(3)

AB = 12
