<h2>The area of the framed photograph = 1156 
</h2>
Step-by-step explanation:
Given,
The length of photograph (l) = 14 inches and
The breadth of photograph (b) = 10 inches
To find, the area of the framed photograph = ?
We know that,
The area of the framed photograph = (l + 2b)(l + 2b)
= (14 + 2 × 10) (14 + 2 × 10)
= (14 + 20) (14 + 20)
= (34) (34)
= 1156
∴ The area of the framed photograph = 1156
For this question, we're going to use the law of cosines.
The law of cosines is the following equation:
We know the values of a, b, and c. We want to find the measure of angle A.
Now, plug in these values into the equation.
Add both sides by
and subtract both sides by 16
Divide both sides by 36
Take the inverse cosine, or arc cosine, of both sides.
Using a calculator, you'll get the following result.
The measure of angle A should be 36.3 degrees. Hope this helps! :)
