Answer and Step-by-step explanation:

We are given:

A side length of 7

An angle of 30.

We will use trigonometric functions to solve for a.

We will use the sine trig function.

[tex]sin(Angle) = \frac{Opposite (Side)}{Hypotenuse (Side)}[/tex]

[tex]sin30 = \frac{7}{a}[/tex]

Multiply a by both sides, then divide by sin30 on both sides.

[tex]a = \frac{7}{sin30}[/tex]

Now, use a calculator and do 7 divided by sin of 30.

We get a to be:

14

a is equal to 14
