What is the ratio of the diameter of the orange circle to the diameter of the blue circle?
a. 4/6
b. 3/2

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct

Many things that seem threatening in the dark become welcoming when we shine light on them
