Step-by-step explanation:
10c2*13c3
10!/(10-2)!2! *13!/(13-3)!3!
[(10*9*8!)/8!*2*1] *[(13*12*11*10!)/10!*3*2*1]
45*286

Explanation
For the given question, we will have to apply the rule for lines intersecting inside a circle
We will simply apply the rule

Thus, the measure of the arc RA is 77.2 degrees
Option D is correct
You get two 90 degree angles
