90+27=117
180-117=63
X=63 degrees
Answer:
B) x = +/- 17
Step-by-step explanation:
The answer should be 16 you add 23.96 to both sides
let t = time (hrs) that they are 50 mi apart
Use pythag here; a^2 + b^2 = c^2; dist = speed * time
(30t)^2 (40t)^2 = 50^2
900t^2 + 1600t^2 = 2500
It's obvious that t = 1 hr
