Answer:
Step-by-step explanation:
Given
Balloon in the east makes an angle of elevation of and is at height of 461 m
Balloon in the west makes an angle of elevation of and is at height of 296 m
Erica height is 1.6 m tall so net altitude of Red balloon is 459.4 m
and net height of Blue balloon is 294.4 m
using trigonometry
Distance between two Balloons
Answer:
15.01
Step-by-step explanation:
For this problem you have to use tangent.
Always know that for tangent it is: opposite side/ adjacent side!
using this knowledge:
tan65= BC/7
7(tan65)=BC
BC= (to the nearest 100th) 15.01
Pythagorean theorem is used to solve this
