Answer:
106°
Step-by-step explanation:
The angle CAB is an inscribed angle of the arc mBC, so we have that:
mBC = 2*CAB
So we have that mBC = 2*37 = 74°
The segment AC is a diameter of the circle, so mAC = 180°
The ? angle is the arc mAB, which is the difference of mAC and mBC, so:
mAB = mAC - mBC = 180 - 74 = 106°
So the ? angle is 106°.
Answer: y should be in the interval (0.4, 4)
Explanation:
The binomial 5y - 7 is in the interval (-5, 13) if and only if
-5 < 5y - 7 < 13
Solving the inequalities in this form is the same as solving equation. So, we add all sides of the inequalities by 7 so that
2 < 5y < 20
Then, we divide both sides by 5 to get the following inequalities
0.4 < y < 4
Hence y should be in the open interval (0.4, 4).
