Bangladesh Junior Maths Olympiad Question |Bangladesh Maths Olympiad #olympiad #imo #bangladesh

If the angle of circle is 360°
The remaining angles are 360–(140+80)=140°
2x=360–140=220°
So, x=220/2=110°
Will this method work?🤨

My answer was 110 too but process different

🇧🇩🖤

there is an easy way to solve it, just use the formula of an angle that is inside a circle:
x= (big arc + small arc) / 2 = (140+80)/2 = 220 /2 = 110 degrees

Good explanation. But i can solve it in another way.,also..

The drawing does not show the intersection at the center otherwise the problem is simple.

x turns out to be the average of 140° and 80°, i.e. x=(140+80)/2=110°. You can so quickly calculate the value of x.

that's nice! thank you

Awesome explanation ❤️

Do we measure arc in degrees? It is always a length units. Yes, it makes an angle at the center of a circle which can be expressed in degrees or in radians.

Nice question 🙃

Nice

Good one more Question on circle please
