Answer:
<D + <F = 
Step-by-step explanation:
Given: <D + <E = 
<E + <F = 
But, the sum of angles in a triangle =
.
Thus;
<D + <E + <F = 
+ <F = 
⇒ <F =
- 
= 
<F = 
Also,
<E + <F = 
<E +
= 
<E =
- 
= 
<E = 
So that;
<D + <E = 
<D +
= 
<D =
- 
= 
<D = 
⇒ <D =
, <E =
, and <F =
.
Therefore;
<D + <F =
+ 
= 
So 12/14 =6/7
so we multiply this by 21 to see how many games they will win
6/7 times 21/1=(6*21)/7=(6*3*7)/7=6*3=18
