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.


sin(Angle) = (Opposite (Side))/(Hypotenuse (Side))


sin30 = (7)/(a)

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


a = (7)/(sin30)

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

We get a to be:

14

a is equal to 14
