Answer:
Option d. 18.7 units
Step-by-step explanation:
step 1
we have
B=17° 55'=17+55/60=17.92°
C=98° 15'=98+15/60=98.25°
step 2
Find the measure of angle A
∠A+∠B+∠C=180°
substitute
∠A+17.92°+98.25°=180°
∠A=180°-(17.92°+98.25°)=63.83°
step 3
Applying the law of sines
c/sin(C)=a/sin(A)
substitute the values
c/sin(98.25°)=17/sin(63.83°)
c=sin(98.25°)*17/sin(63.83°)
c=18.7 units
x = - ![\frac{8}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B3%7D)
isolate - 6x by subtracting 9 from both sides
- 6x = 16 ( divide both sides by - 6 )
x =
= - ![\frac{8}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B3%7D)
300 miles.
1 inch is 200 miles
half an inch is 100 miles
200 plus 100 equals 300 miles
18x+6y = 6(3x+y)
