Solution

The correct option is A $110^{\circ}$ , $70^{\circ}$
a = $110^{\circ}$ [Vertically opposite angles]

b = $180^{\circ}$ – a [Interior angles on the same side of transversal]

= $180^{\circ}$ – a

= $180^{\circ}$ – $110^{\circ}$

= $70^{\circ}$

Find the value of angles a and b in the following figure.

The correct option is A 110∘, 70∘a = 110∘ [Vertically opposite angles] b = 180∘– a [Interior angles on the same side of transversal] = 180∘– a = 180∘ – 110∘ = 70∘

The correct option is A $110^{\circ}$ , $70^{\circ}$
a = $110^{\circ}$ [Vertically opposite angles]

b = $180^{\circ}$ – a [Interior angles on the same side of transversal]

= $180^{\circ}$ – a

= $180^{\circ}$ – $110^{\circ}$
