Respuesta :

#a

m<5=40°

  • Reason-Its Given

#b

m<2=140

  • Reason-Given

#c

<5 and <2 are linear pair(looked properly in diagram) Hence they are supplementary.

#d

<5 and 2 are same side interior angles (Clearly shown on diagram .

  • We can call them co responding interior angles and their sum will be 180 if lines are parallel

#e

a||b

Let's verify

Let the angle below <1 be <3

Now

<2+<3=180

<5+<4=180

  • <5=<2

[tex]\\ \sf\longmapsto <5+<2=180[/tex]

Hence verified
