Question

i need to take out the x
o= 104
third angle I don't know​

Answer 1

one angle is given that is 104 degree...ok...

then...from centre o there are two lines upto circle....these are radius...and radius are always equal.....it means the triangle is an isosceles triangle.....

and one property of isosceles triangle is that the two angles opposite to equal sides are equal...it means the remaining two angles are of equal measure.. I hope you understood upto here

Now.. 104 + x + x =180

2x=76

x=38

I hope you got your answer.. really great question it was...
