Answer:
Step-by-step explanation:
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:

When two straight lines or rays intersect at a shared endpoint, an angle is generated. The correct option is A.
<h3>What is an angle?</h3>When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."
The diagram for the given problem can be made as shown below. Therefore, the other name for angle 2 will be ∠DGE.
Hence, the correct option is A.
