Answer 1

Answer:

As sum of all angles in triangle is 180°,quadrilateral has 360°,pentagon has 540°..

In the same way pentagon has 720°..

So if we add up all the angles given in figure..

We get, 75+110+170+130+90=575

Then subtract 575 from 720 then we get

145

So the correct answer is

Option "A" 145°
