Answer:
4 + 14b
Step-by-step explanation:
First, you need to distribute so,
2*2= 4 and
2*7b= 14b
The common difference, d, is 5 and the starting value, a, is 2.
Filling this in the form of

OK for this question you need to find out how many more post are needed. If you look at the diagram it shows that one side is 50 feet. Now there are two sides that will need post, because the barn side need no more. Now if there are two side both 50 feet, and you need a post every ten feet. How many posts are needed?
Answer:
68.9°
Step-by-step explanation:
Using Sine rule
x/sin X = y/sin Y
4.5/sin X = 4/sin 56
sin X × 4 = 4.5 × sin 56
sin X = 4.5 × sin 56/4
X = arc sin (4.5 × sin 56/4)
X = 68.85449°
Approximately = 68.9°
