Answer:
357÷12
Step-by-step explanation:
You need to figure out how many are in one so you would have to divide it by 12 to get your answer.
The correct question is
<span>What is the equation in standard form of an ellipse centered at the origin and vertex (4,0) and focus (1,0)
</span>
we know that
<span>Standard form of equation for an ellipse with horizontal major axis is
(x-h)</span>²/a²+(y-k)²/b²=1
the center is the origin
so
(h,k) is (0,0)<span>length of horizontal major axis------> 8=2a-----> a=4
a</span>²=16
c=1 (distance from center to focal point)
c²=1
b²=a²-c²-----> b²=16-1----> b²=15
the equation is
(x)²/16+(y)²/15=1
the answer is
(x)²/16+(y)²/15=1
Let 1 angles be x, then its supplement is 180-x
x+x+12=180
2x=168
x=84
angles are 84 and 96
