Answer:
SA = 7.97 km
SB = 31.3 km
Step-by-step explanation:
Draw a picture of the triangle formed by the points A, B, and S.
∠SAB = 137°, and ∠ABS = 10°. Therefore, ∠ASB = 33°.
Using law of sines:
25 / sin 33° = x / sin 10°
x = 7.97
25 / sin 33° = y / sin 137°
y = 31.3
Round as needed.
The value of c from the equation is 5.
c/5 - 4 = -3
Add 4 to both sides of the equation.
c/5 = 1
Multiply both sides by 5 to get c by itself.
c = 5
