Question

ABCD is a ||GM which Angle a ,3x-50 and b=x+40 find x​

Answer 1

Answer:

Step-by-step explanation:

*opp angles of a parallelogram are equal and the sum of all angles is 360 *

angle A = angel C and angle B = angle D

so, angle A + angle B+ angel C+ angle D = 360

2(3x-50)+2(x+40)= 360

3x-50+x+40 = 180 (taking 2 common)

4x-10= 180

4x= 190

x= 190/4

x= 47.5
