Answer:
2.2
Step-by-step explanation:
To find a, you use a formula called the law of cosines:
The law of cosines tells us:
a^2 = b^2 + c^2 - 2bc cosA
So lets plug in the values:
a^2 = 4^2 + 3^2 -2(4)(3)cos(32)
a^2 = 25-24cos32
a^2 is roughly equal to 4.97
therefore a roughly equal to 2.2

The ''trick'' I like to use to convert decimals to percents is this:
CHANGING A DECIMAL TO PERCENT, MOVE 2 SPACES TO THE <u>RIGHT
</u>CHANGING A PERCENT TO A DECIMAL, MOVE 2 SPACES TO THE <u>LEFT
That's an easy way to memorize the conversions between decimals and percents.
