Question

In parallelogram ABCD, angle A is equal to 3 times angle B. Find all the angles of the parallelogram. In the same parallelogram, if AB is equal to 5x-7 and CD is equal to 3x plus 1, find the length of CD​

Answer 1

Answer:

In parallelogram opposite sides are equal

AB=CD

5x-7=3x+1

5x-3x=7+1

2x=8

x=8/2

x=4

now we substitute value of x in 3x+1

=3(4)+1

=12+1

=13

therefore CD=13
