Is there a way out?

My problem in Maths is only with application of theorems. So please help me by suggesting some ways to do it well. I got 2 theorem questions wrong in my exam. If this is only my problem should I go to some special tuitions for maths to score well? Please help me out

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

OIC. For this question you need some theorems which are useful in angle tracing in circles:
arc proportional to subtended angle
angles in semi-circle
And a basic one:
angle sum of triangle
Are you familiar with these theorems?

Yes I am familiar with these theorems except the first one you mentioned.

It states that if there are two arcs on a same circle, the ratio of length of these two arcs equals the ratio of the angle (at circumference or at centre, both OK) subtended by these two arcs respectively.
