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! :)

The perimeter and area of the square are 16√5 mm and 80 mm²
<h3 /><h3>How to find perimeter and area of a square?</h3>Perimeter of a square = 4L
where
- l = length
Therefore,
Perimeter of a square = 4 × 4√5
Perimeter of a square = 16√5 mm
Area of a square = l²
Area of a square = (4√5)²
Area of a square = 16 × 5
Area of a square = 80 mm²
