Given:
Angle A = 18.6°
Angle B = 93°
Length of side AB = 646 meters
To find:
the distance across the river, distance between BC
Steps:
Since we know the measure of 2 angles of a triangle we can find the measure of the third angle.
18.6° + 93° + ∠C = 180°
111.6° + ∠C = 180°
∠C = 180° - 111.6°
∠C = 68.4°
Therefore the measure of angle C is 68.4°.
now we can use the law of Sines,
![BC[sin(68.4)] = 646 [sin(18.6)]](https://tex.z-dn.net/?f=BC%5Bsin%2868.4%29%5D%20%3D%20646%20%5Bsin%2818.6%29%5D)
meters
Therefore, the distance across the river is 222 meters.

Find slope by calculating rise over run.
-6-4 / 2-(-3)
-10/5
-2
Then plug one set of coordinates and the slope in to find the b value
-6= -2(2)+b
-6=-4+b
-2=b
Final answer: y=-2x-2
Answer:
5390 gallons of water was wasted by the city's residents last year.
Step-by-step explanation:
Let 
denotes gallons of water wasted by the city's residents last year.
Gallons of water wasted by the city's residents this year = 2695 gallons
This is 50% less than last year.
Therefore,
gallons
So, 5390 gallons of water was wasted by the city's residents last year.
