Question from light: ABCD is a parallelogram. If angle A. = (4x=17)degrees and angle B. = (3x-5)degrees , what is angle c? |
Light,
This is a parallelogram ABCD so angle A = angle C and angle B = angle D. Thus the sum of the 4 interior angles is
2(4x - 17) + 2(3x - 5) degrees
What is the sum of the interior angles of a quadrilateral?
Solve for x.
