Answer:
a. the coordinates of g = 1 and -5
explanation
x-1=0 OR x+5=0
collect like terms
x=1. OR x=-5
A
using the Cosine rule in ΔSTU
let t = SU, s = TU and u = ST, then
t² = u² + s² - (2us cos T )
substitute the appropriate values into the formula
t² = 5² + 9² - (2 × 5 × 9 × cos68° )
= 25 + 81 - 90cos68°
= 106 - 33.71 = 72.29
⇒ t = ≈ 8.5 in → A
I'm pretty sure it's 114 miles.
