Can somebody please help me with question number 2 ?

75 Degrees

Step-by-step explanation:

We know that all the angles of a triangle add up to 180.

We also know the each angle of triangle DEF in terms of variables

All we have to do is add the 3 angles which equal a total of 180 Degrees.

Angle D+E+F = 180 Degrees

(5+x) + (6+4x) + (4x) = 180

9x + 11 = 180

9x = 169

x = 18.8 Degrees

Angle F is 4x so it is 4(18.8) = 75 Degrees

This is what i got, I"m not sure what else im supposed to solve for. The multiple choice doesnt make sense.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
