Step-by-step explanation
We are told that the tangent of an angle x is equal to 0.9004. In order to solve this equation for x we can use the arctangent function that has this property:
Then we can apply the arctangent to both sides of our equation:
So our angle is the arctangent of 0.9004 which can be found using a calculator. However calculators oftenly work with radians and we need to express x in degrees. In order to transform the result from radians to degrees we have to perform the following operation:
