Find the value of x in a triangle with one side 11 and 1 angle being 28

Andre45 [30]

Answer:

C: 12.5

Step-by-step explanation:

The sides x and 11 could be defined as the Adjacent angle and the Hypotenuse. This means that we will use the cos function to solve this.

First we can set up our equation

$cos28=\frac{11}{x}$

Next we can solve for x by multiplying by x and dividing by $cos 28$

$x=\frac{11}{cos28}\\\\x=12.458\\\\x=12.5$
