Hello! Remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any figure, so I'll assume m∠1 and m∠2 are complementary angles. Angles that add up to 90° are called complementary angles. In this case, we know m∠1 and want to know m∠2. Thus, we can establish the following formula:
m∠1 + m∠2 = 90°
Isolating m∠2:
m∠2 = 90° - m∠1
m∠2 = 90° - 64
m∠2 = 26°

hope this helps :)
edit: just saw the answer choices, the answer should be b.0.2
(2 x 3.95) + (3 x 4.25) + (1 x 5.99) + ((2 x 3.95) + (3 x 4.25) + (1 x 5.99)) x 0.20
= 26.64 - 5.32
= 21.32
