Instead of adding or subtracting 2pi (that's for radians only), just add or subtract 360 degrees to your angle.

Answer:
see below
Step-by-step explanation:
1/2 = q + 2/3
Subtract 2/3 from each side
1/2 -2/3 = q+2/3-2/3
Getting a common denominator of 6
3/6 - 4/6 = q
-1/6 =q
p - 3 1/6 = -18.73
Add 3 1/6 to each side
p - 3 1/6 + 3 1/6 = -18.73 + 3 1/6
p = -18 73/100 + 19/6
Get a common denominator
p =- 5619/300 + 950/300
= -4669/300
=-15 169/300
Answer:
The common difference of the progression is 3.
Step-by-step explanation:
Given:
First term of the AP = (a) = -8
Ratio of 7th and 9th term = 5:8
So,
General term of an AP, Tn= a+(n-1)d
Where 'd' is the common difference.
equation...(i)
equation...(ii)
According to the question.
⇒ 
...cross-multiplying the terms.
⇒ 
⇒ 
⇒ 
...subtracting 40d and adding 64 both sides.
⇒ 
⇒ 
...dividing both sides with 3.
So the common difference of the progression is 'd' = 3.
Answer:
11
Step-by-step explanation:
Well since you need two halves to make a whole i did 5*2 and got 10 then added the extra 1/2 and got 11 houses
