Answer:
4)a=50
b=50
c=130
d=50
5) a=90
Step-by-step explanation:
4) angle 50 =angle a =50 { alternate interior angle are equal}
angle b = angle a=50 {vertically opposite angle are equal}
angle 50= angle d =50{corresponding angle are equal}
angle c= 180-angle d
=130
i.e angle a=angle b= angle d=50
angle c= 130
5)as second line is parallel to last line
angle a = 65+ 25 = 90{alternate interior angle are equal}
i.e angle a = 90
