i think it correct but if it not it okay but alaest I try my best on it
We know that the sum of the interior angles of a triangle equals 180, then,in this case we have the following equation:

then, solving for b, we get:

now that we have that b = 41, we can find the measure of each angle:
Cos 52 = 0.6157
sin 42 = cos 48 = 2/3 (because 42 + 38 = 90 - complementary angles)
if tan 20,5 = 3/8 then tan 69.5 wil = 1 / 3/8 = 8/3
Answer:
14 + j = 28
