Answer:
difference = 3, first term = 4
Step-by-step explanation:
given, a2 = 7
a9 = 28
wkt, a2 = a + d = 7
<u>a9 = a + 8d</u><u> </u><u>=</u><u> </u><u>28</u>
- 7d = - 21
therefore d = 3
and wkt, d = a2 - a
a = 7 - 3 = 4

Use the sine theorem:
sin(angle A) / length of side a = sin (angle B) / lenght of side b
Here:
angle A = 32°
length of side a = length from school to library = x
angle B = 110°
length of side b = 2.2 mi
Then, sin(32°) / x = sin(110°) / 2.2 mi
=> x = 2.2 mi * sin (32) / sin (110)
x = 1.24 mi
Therefore the answer is the option B. 1.2 mi
