Question

can any one answer me please

Answer 1

Given that two opposite angles of a parallelogram are (63 - 3x) and (4x - 7).

We know that opposite angles of a parallelogram are equal.

63 - 3x = 4x - 7

-3x = 4x - 70

-7x = -70

x = 10.

Then,

63 - 3x = 63 - 3(10)

            = 63 - 30

            = 33.


We know that Sum of adjacent angles is 180.

Hence the other two equal opposite angles = 180 - 33

                                                                          = 147.


Therefore the angles of a parallelogram are 33, 147, 33 and 147.


Hope this helps!
