Answer:
To find the angle A in the right triangle, we can use the inverse of the sine function, also known as arcsine. The arcsine function can be used to find an angle when the ratio of the opposite leg to the hypotenuse is known.
In this case, the ratio of the opposite leg to the hypotenuse is 0.23. To find the angle A, we need to find the angle whose sine is 0.23.
Using a calculator or a table of values, we can find that the angle whose sine is approximately 0.23 is about 13.5 degrees.
Therefore, a reasonable approximation for angle A is approximately 13.5 degrees.
