Answer:
<em>I've attached a picture of a unit circle with the quadrant labeled. </em>
<u>Calculate the degree of 5п 8 radians:</u>

<u>Locate the general location of 112.5° on the unit circle:</u>
It's between 120°(
) and 90°(
).
<u>Find the quadrant it lies in:</u>
Quadrant II
Answer:
Therefore the value of 
Step-by-step explanation:
Given:
m∠ A = 56°
m∠ B = 75°
m∠ ACD = x°
To Find:
x = ?
Solution:
In Δ ABC
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
Here,
The opposite interior angles are angle A and angle B.
An exterior angle of a triangle is angle ACD which is x°
∴
...Exterior angle property of Δ
Substituting the values we get

Therefore the value of 
Answer:875
Step-by-step explanation:
I know it
Answer: 1.67
Step-by-step explanation:
Z = ( x - mean) / standard deviation
Z = (97-75) / 12
= 20 / 12 = 1.67
40,000 + 9,000 + 500 + 60 + 4.
