Final Answer: The value of α that satisfies the given statement is 37.835888

Steps

Step 1 :The cotangent of an angle is the reciprocal of the tangent of the angle. Therefore, to find the angle whose cotangent is 1.2875262, we can take the reciprocal of 1.2875262 to get the tangent of the angle.

Step 2 :cotα=1.2875262

Step 3 :tanα=1cotα=11.2875262=0.7766832239996359

Step 4 :Then, we use the arctangent function to find the angle. The arctangent function returns the angle in radians, so we will need to convert it to degrees.

Step 5 :αrad=arctan(tanα)=arctan(0.7766832239996359)=0.6603608158105972

Step 6 :αdeg=αrad×180π=37.835888

Step 7 :Final Answer: The value of α that satisfies the given statement is 37.835888
