Can some help me with this one please??

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]
