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
