Question

In the given figure, L ll m and PQ ll RS. If angle1 = 100 degree, find the measures of the remaining angles. ( please tell the solution ) ​

Answer 1

Answer:

as PQ is straight line:

<1+<2=180

So, ,2=180-<1

<2=180-100

[<2=80]

<3+<2=180

<3=180-<2

<3=180-80

[<3=80]

as, PQ||RS

<2=<6(alternate interior angles)

[<6=80]

<3=<4(alternate interior angles)

[<4=100]

<5=<6(Vertically Opposite Angle)

[<5=80]
