Answer:

The missing angle is 60⁰

The length of side a is 12.12

The length of side c is 14

Step-by-step 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;

[tex]tan (30) = \frac{7}{a} \\\\a = \frac{7}{tan(30)} \\\\a = 12.12 \ units[/tex]

The length of side c is calculated as follows;

[tex]sin(30) = \frac{7}{c} \\\\c = \frac{7}{sin(30)} \\\\c = 14 \ units[/tex]
