Answer:
<em>m<A = 40 deg</em>
<em>m<B = 60 deg</em>
<em>m<C = 80 deg</em>
Step-by-step explanation:
2x + 3x + 4x = 180
9x = 180
x = 20
m<A = 2x = 2(20) = 40
m<B = 3x = 3(20) = 60
m<C = 4x = 4(20) = 80
m<A = 40 deg
m<B = 60 deg
m<C = 80 deg

Answer:
degrees Fahrenheit
Step-by-step explanation:
Let 
be temperature.
at 3:00PM: 
degrees.
Every hour, the temperature falls by 
degrees per hour for the next four hours. Let's multiply 2.5 by 4 to find out the total temperature drop in four hours.
In four hours, the temperature dropped 10 degrees. Since it is getting colder, let's subtract this from the original 5.5 degrees to get the temperature at 7:00PM.
The temperature at 7:00PM was -4.8 degrees Fahrenheit.
