Question

What size of target angle is required for the radiation to cover a 14-in x 17-in IR at a distance of 40 inches?

a. 8 degrees
b. 12 degrees
c. 16 degrees
d.20 degrees

Answer 1

To determine the size of target angle required for coverage, use the properties of angles and similar triangles to set up an equation. Solve for the angle using trigonometric functions.

Step-by-step explanation:

In order to calculate the size of target angle required for the radiation to cover a 14-in x 17-in IR at a distance of 40 inches, we need to consider the properties of angles and similar triangles.

Using the properties of similar triangles, we can set up the following equation: 14 / (40*cos(angle)) = 17 / (40*sin(angle))

Solving this equation will give us the value of the angle. By using trigonometric functions and solving the equation, we find that the correct answer is 16 degrees (option c).
