Question

The angles of a quadrilateral are 50° and 80° respectively. The other two angles are equal. Find them.​

Answer 1

Answer:

We know

Sum of all angles of a regular quadrilateral=360°

that is all angles will make up a sum of 360°

Given other 2 angles are equal,let them be x each

therefore the equation is

50+80+x+x=360

130+2x=360

2x=360-130=230

x=230/2

x=115°

therefore the angles are

115°

115°

80°

50°

Let's check whether it's correct or not

(115+115)+(80+50)=360°

230+130=360

360=360

L.H.S=R.H.S

hence verified
