What is an equation in standard form of an ellipse centered at the origin with vertex (-7,0)
and co-vertex (0,5)?
a)x^2/5+y^2/7=1
b) x^2/7+y^2/5=1
c) x^2/25+y^2/49=1
d)x^2/49+y^2/25=1

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
