Step-by-step explanation:

Let θ is the angle between the tangents

Let a line y=mx+c is tangent to

the ellipse

25

x 2+ 16y 2 =1

then c= 25m 2+16

y=mx+

25m 2+16

It passes through (6, 5)

( 5 −6m) 2=(25m 2 +16)

36m 2+5−12 root=25m 2+16

11m 2−12 root5m−11=0

m 1m 2= 11/11 =−1

Tangents are perpendicular

θ=90 ∘
