Answer for question 14 is option c)10cm

I didnt get the first one.I got different answer : (

shemanourinep: On substituting the value in the equation we get the height=5 cm(60÷12)

shemanourinep: By drawing the height/altitude inside the parallelogram, we can form a right angled triangle with one angle 30 degree

shemanourinep: 30 degree is given in the question.The angles of the triangle will be 30,60,90.Therefore sides will be of the ratio 1:root3:2

shemanourinep: length of side opposite to angle 30 is 5cm.So the other side of parallelogram which is the side opposite to the angle 90 will be 5×2=10cm

shemanourinep: Hope you understand

shemanourinep: I couldn't take photo of the answer.Sorry.So I tried to explain it in this way

abhi6803: Ok, Thanks.
