Question

Draw a triangle of two sides 5.9cm and 6.9cm and included angle is 45°. Now construct a parallelogram whose area is equal to the given triangle and one angle is 30°​

Answer 1

H^2=P^2+B^2

(6.9)^2=(5.9)^2+B^2

47.61= 34.81+B^2

Step-by-step explanation:

To know the third side of triangle use Pythagoras Theorem. Draw a triangle as given and then make a parallelogram connects with the base of triangle and because of Pythagoras Theorem we know the one side of the parallelogram and due to the property we know the other side also and join the opposite angles of parallelogram and then by herons formula we will get the answer.
