Question

hi

can anyone help me fast ​

Answer 1

6.  A=75 degree

we know that,

opposite angles of parallelogram are equal

=> A=C &B= D ----------(i)

=> c= 75 degree

in parallelogram

A + B+ C + D = 360 degree [ sum of all angles of a quadrilateral is 360 degree]

75 + B + 75 + D =360

150 + 2B = 360 [from i]

2B = 210

B = 105

=> D = 105

therfore, B=105, C = 75, D = 105

Hope it helps....
