The figure shows a right triangle.
To calculate the measure of the angle A, you can use the inverse trigonometric function arctangent:
Identify the angle 
, the opposite side and the adjacent side:
Substitute into .
The measure of the angle A is:
Rounded to the nerarest hundreth:
(4*1000) + (2*100) + (3*1/10) = <span>4200.3
</span>(4x1000) + (2x100) + (3x1/10) = <span>4200.3
</span>
Both are equal.
