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.


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

Now, use a calculator and do 7 divided by sin of 30.
We get <em><u>a</u></em> to be:
14
<u>a is equal to 14</u>
