Answer:

The missing angle is 60⁰

The length of side a is 12.12

The length of side c is 14

Explanation:

The missing angle is a complementary angle which is calculated as follows;

θ = 90 - 30

θ = 60

The missing angle is 60⁰

The length of side a is calculated as follows;

$tan (30) = (7)/(a) \\\\a = (7)/(tan(30)) \\\\a = 12.12 \ units$

The length of side c is calculated as follows;

$sin(30) = (7)/(c) \\\\c = (7)/(sin(30)) \\\\c = 14 \ units$
