Question

In the green figure, Best is a kite
in which - to remaining
tus angle​

Answer 1

Step-by-step explanation:

BT=TS

therefore, angle TBS and angle TSB are equal

therefore, angle TBS + angle TSB + angle BTS = 180° (angle sum property of ∆)

= angle TSB + angle TSB + angle BST = 180° (angle TBS = angle TSB)

= 2angle TSB + angle BST =180°

=2angle TSB + 80° =180°

= 2angle TSB = 180°- 80°

= 2angle TSB = 100°

= angle TSB = 100÷2

= angle TSB = angle TBS = 50°
