The total height from flash light to the keys is 1.6 + 0.5 = 2.1 meters

the vertical angle = 40 degrees

the horizontal distance =  2.1 x tan(40)

distance = 1.76 meters  ( round answer as needed )

How many solutions does this equation have? How do you know?<br><br> 8x +14 - 4x = 9 + 4x - 5
MAVERICK [17]

Answer:

no solutions.

Step-by-step explanation:

8x + 14 -4x = 9+4x -5

8x-4x -4x = 9-5-14

0x = -10

anything multiplied by 0 is 0, so it's impossible to get -10 by multiplying by 0
