Question

the adjacent angles of a rhombus are in the ratio 1:2 each side is 12 CM of all angle and length of diagonal smaller​

Answer 1

We know that some of adjacent angles of rhombus is 180°

and also let angles of rhombus be 1x and2x

So, 1x +2x=180°

3x=180°

x=180/3

x=60°

1x=60×1=60°and2x=2×60°=120°

So angles of rhombus are 60°,120°,60°and120°

other ngles are also 60°and120°because opposite angles of rhombus are same
