Problema Solution
Two consecutive angles, Angle C and Angle A of parallelogram CARE are (3x+15)degrees and (6x-15)degrees respectively. Find the value of x and all the angles of the parallelogram.
Answer provided by our tutors
Angle A = 3x + 15
Angle C = 6x - 15
Since A and C are angles in parallelogram we have:
Angle A + Angle C = 180
3x + 15 + 6x - 15 = 180

........
x = 20
Angle A = 3*20 + 15
Angle A = 75 degrees
Angle C = 6*20 - 15
Angle C = 105 degrees.
