C^2 = A^2 + B^2
C^2 = 15^2 + 20^2
C^2 = 225 + 400
C^2 = 625
C = √(625)
C = 25
The answer would be d=8t
This would be because the time they want is 1 hour. So when you plug in t as 1 you need d to equal 8. So you just have to change that 6 in the first equation to an 8. This new equation means that the person can travel 8 miles every hour.
The location of the sensor that it is opposite the direction of the wind is reasonable and is needed to identify the plant's emissions. However, there might be a bias to that if it is located a mile from the plant's smokestack. The distance may be quite far. Considerations in identifying the location of the sensors such as changes in wind direction, wind speed, atmospheric stability, physical stack height, diameter, and other important factors are needed to have an accurate reading of the pollutants.
The 3 inside angles of a triangle equal 180.
Add the 3 angles together to equal 180:
X + (5x-20) + 4x = 180
Simplify the left side by adding like terms:
10x-20 = 180
Add 20 to each side:
10x = 200
Divide both sides by 10:
x = 20
Angle A = x = 20
Angle B = 4X = 4(20) = 80
Angle C = 5x-20 = 5(20) -20 = 100-20 = 80
