Answer:
The correct answer is C. 224
Step-by-step explanation:
Sn = n/2 (2*A1 +d(x-1))
S7=7/2(2*17+5(7-1))
S7=7/2(34+30)
S7=7/2(64)
S7=7*64/2
S7=7*32/1
S7=224
Hope This Helps, If So Mark As Brainliest! :)

Answer:
34.6 ft
Step-by-step explanation:
The distance can be found using the Pythagorean theorem. Where a, b, c are the sides of a right triangle with c as the hypotenuse, it tells you ...
a² + b² = c²
a = √(c² -b²)
base-to-string = √(39² -18²) = √1197 ≈ 34.598
The distance from the base of the pole to the end of the string is about 34.6 feet.
X comes first, then y....so ur points are (-5,3)
