Answer 1

Let equation of ellipse

x² / a² + y² / b² = 1 and a> b

In this case major axis is x axis and

Length of major axis = 2a

and

Coordinates of foci = (±ae , 0 )

Now we have to find equation of ellipse i think

ATQ

Length of major axis = 26

2a = 26

a = 13

Coordinates of foci = ( ±5 , 0 )

( ± ae , 0 ) = ( ±5 , 0 )

On comparing we get

ae = 5

Putting a = 13 in it

( 13 ) e = 5

e = 5 /13

Now we have a formula

b² = a² ( 1 - e² )

= a² - a² e²

= ( 13 )² - ( ae )²

= 169 - ( 5 )²

= 169 - 25

= 144

Equation of ellipse

x² / a² + y² / b² = 1

x² / 169 + y² / 144 = 1
