Final Answer: The value of θ that satisfies the given statement is approximately 28.535110

Steps

Step 1 :We are given the cosine of an angle and we need to find the angle itself. We can use the arccos function (also known as the inverse cosine function) to find the angle. The arccos function returns the angle in radians, so we will need to convert it to degrees.

Step 2 :Given that cosθ=0.87852455

Step 3 :Calculate the arccos of 0.87852455 to get the angle in radians: θrad=arccos(0.87852455)=0.4980316258984871 radians

Step 4 :Convert the angle from radians to degrees: θdeg=θrad×180π=28.535110228021615 degrees

Step 5 :Final Answer: The value of θ that satisfies the given statement is approximately 28.535110
