Final answer:
To find the triangle in which the value of x is equal to arctan(3.1/5.2), we need to use the inverse tangent function and solve for the angle. Once we have the angle, we can determine the triangle.
Step-by-step explanation:
In this question, the value of x is equal to tan-1(3.1/5.2). To find the triangle in which this value is equal to, we need to use the inverse tangent function or arctan. arctan(3.1/5.2) will give us the angle whose tangent is equal to 3.1/5.2. Once we have this angle, we can determine the triangle based on the value of x.
