Step-by-step explanation:
<em>The question is incomplete as the image that illustrates the scenario is not given.</em>
<em>However, I can deduce that the question is about a right-angled triangle.</em>
<em>So, I will give a general explanation on how to find each of the side of the triangle, given a side and an angle.</em>

<u>For triangle A (solve for b)</u>
Using cosine formula.
Make b the subject
<u>For triangle B (solve for b)</u>
Using cosine formula.

Make b the subject
Answer:
Below in bold.
Step-by-step explanation:
2x + 18 + 3x + 12 = 180 (property of a cyclic quadrilateral).
5x = 180 - 18 -12
5x = 150
x = 30
So m < A = 2(30)+18
= 78 degrees.
