Answer:
All sides in a Rhombus are equal.
so, now we get two triangles with the same base TL i.e. The common side.
Since all the sides of a Rhombus have the same length we could say that KT=TA=Al=LK.
We can say that ∠TLA =∠LTA=50°.
The Sum of All the angles of a triangle is 180°.
∠TLA + ∠LTA + ∠TAL = 180°
∠TAL = Y
50° + 50° + Y = 180°
100° + Y = 180°
Y = 180° - 100°
Y = 80°
∴ ∠TAL = Y = 80°.
Hope it helps you.
