Question

in Qs.4,5, Find each of the lettered angles giving reason.​

Answer 1

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
