Distance formula : sqrt (x2 - x1)^2 + (y2 - y1)^2
(212,23)...x1 = 212 and y1 = 23
(6,23)......x2 = 6 and y2 = 23
now we sub
d = sqrt ((6 - 212)^2 + (23 - 23)^2)
d = sqrt ((- 206)^2 + (0^2))
d = sqrt (42436 + 0)
d = sqrt 42436
d = 206 miles <==

1. use sin
inverse of sin(44/57) = 50.5 ---> 51°
2. use tan
inverse of tan(6/8) = 36.8 ---> 37°
3. use cos
inverse of cos(20/31) = 49.8 ---> 50°
4. use sin
inverse of sin(37/58) = 39.6 ---> 40°

Answer:
3
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a +(n - 1)d
where a is the first term and d the common difference
Given the fifteenth term is - 67, and term 21 is - 97, then
a + 14d = - 67 → (1)
a + 20d = - 97 → (2)
Subtract (1) from (2) term by term
6d = - 30 ( divide both sides by 6 )
d = - 5
Substitute d = - 5 into (1)
a + 14(- 5) = - 67
a - 70 = - 67 ( add 70 to both sides )
a = 3
Thus the first term is 3
