Answer:
a) 
b) 
Step-by-step explanation:
<u>Coterminal angles</u> have the same terminal sides in standard position.
a) To find an angle between 
and 
, that is coterminal with 
, we keep adding multiples of until we get an angle within the specified range.
.
In some cases you would have to subtract in order to get the specified angle. That is when the angle given is positive.
b) This time we want to find an that coterminal with radians.
We keep subtracting multiples of 
until we get an angle measure within the specified range.
8a + a - 3 = 6a - 2a - 3
1. Add the a's on both sides:
9a - 3 = 4a - 3
2. Shift 4a to the left and -3 to the right of the equals sign (this changes their signs):
9a - 4a = -3 + 3
3. Simplify:
5a = 0
So a = 0
Answer:
1/2(m∠JKL) = m∠JKM
Step-by-step explanation:
The angle JKL is being bisected by line KM. This means that the angle has been split into 2 equal angles. Therefore, one of these angles will be equal to 1/2 of the large angle. So, option B, 1/2(m∠JKL) = m∠JKM, is correct.

Step-by-step explanation:
Answer:
38.25 cm²
Step-by-step explanation:
We use the formula for the length of an arc to find the central angle of the sector of the circle.
Then we use the formula for the area of a sector of a circle to find the area.
Length of arc of circle of radius r:
s = arc length
n = measure of the central angle of the sector
Area of sector of circle of radius r:
A = area of sector of circle
n = measure of the central angle of the sector
