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:
Step-by-step explanation:
We know
in the third quadrant 
We use a scientific calculator to find the inverse cosine of -0.9041 to find
Since this angle is not in the required quadrant we must find the other angle who has the same cosine. The required angle is equidistant from the found value from the 180 degrees angle, so our solution is
1. 3x - 4y = 20
2. x - 3y = -6
Answer:
24
Step-by-step explanation:
multiply 10 by 1.5 to get 15.
do the same with 16
0.000038 = 3.8e-5 = 3.8×10⁻⁵
