Answer: d=70; f=45; e=65
Step-by-step explanation:
NUMBER 1 WAY
110+d=180
d=70
135+f=180
f=45
d+f+e=180
70+45+e=180
e=65
--------------------------------------------------
NUMBER 2 WAY
concept to know: exterior angle theorem
------------------------------
System of equation
d+e=135
f+e=110
d+e+f=180
------------------------
d=135-e
f=110-e
-------------------------
d+e+f=180
(135-e)+e+(110-e)=180
135-e+e+110-e=180
245-e=180
e=65
-----------------------
d=70
e=65
f=45
If it there are two negative #'s you add them because they are on the same side of the number line.
Answer:
28/33
Step-by-step explanation:
We first let 0.84 be x.
Since x is recurring in 2 decimal places, we multiply it by 100.
100x=84.84
Next, we subtract them.
100x−x=84.84−0.84
99x=84
Lastly, we divide both sides by 99 to get x as a fraction.
x=84/99
=28/33
