Answer 1

Answer:

Step-by-step explanation:

ANGLE B = 120 DEGREE ( SUM OF ANGLE IN A STRAIGHT LINE IS 180 DEGREE)

ANGLE A = 90 DEGREE ( SAME REASON)

ANGLE D = 360 - 120 +90 +75

75 DEGREE

Answer 2

Answer:

Since a straight line makes an angel of 180 degree

Here 90 degree + a =180

a=180190=90

60 degree +b=180

b=180-60=120

75 degree + c=180

c=180-75=105

Also sum of all angles of a quadrilateral =360

a+b+c+one angle =360

One angle =360-(90+120+105)

360-315=45 degree

45 degree +d=180

d=180-45=135
