A forest ranger sights a fire directly to the south. A second ranger, 7 miles east of the first ranger, also sights the fire.
The bearing from the second ranger to the fire is Upper S 22 degrees Upper W. How far is the first ranger from the fire?
1 answer:
Answer:
17 miles
Step-by-step explanation:
Let the first Ranger be at A and the second Ranger at Point B.
Using alternate angles, ∠AXB=22°.
We want to determine the distance of the first ranger at point A to the fire(X).
Using trigonometry,
Tan = Opposite/Adjacent
Tan 22°= 7/|AX|
|AX| X Tan 22°= 7
|AX| = 7/Tan 22°=17.32560797391
= 17 miles( to the nearest mile)
The first ranger is 17 miles from the fire.
