Question 1
In a ∆ABC, ∠B + ∠A=110 ° and ∠A + ∠C =100 °. Find the value of ∠C.
Question 2
If the radius of a circle is increased by 12% then its area increases by
Question 3
Two chords AB and CD of a circle with centre O and radius 6 cm intersect each other internally at point G. The chord AB is produced to point E and a tangent from point E is drawn which touches the circle at point F. Then find the length of OE if given, AG=2 cm, CG =3 cm, EA= 12 cm and GD= 4 cm.
