Find angle in kite?

Answer 1

What grade is this for?

Answer 2

sum of all angle of kite is 360, Angle S and Angle U are equal so 360 - 120 - 2*100 = 60

Answer 3

How to prove those two angles are equals? join the diagonals, then triangle RUT and RST are similar due to SSS property so opposite angle of common side will be equal.

Answer 4

@baljeet16 Are you sure it's 60? Isn't the correct answer 20?

Nope 40, sorry typo. 200+120 = 320 so 360-320 = 40
