because triangle angles always equal 180, and 90 is already given, so that means that there is 90 left, so divide 90 by two and you get x= 45

Simply draw the triangle and measure the angle. This is how engineers solved those types of problems all the time before computers were a thing.

Tan x = 8/10

Tan x = 0.8

x = 38.6598

It can't be 45 because both sides aren't equally long dumbasses.

Did you get 0.01396etc?

You have to use arctan, not tan.

The arctan of 0.8 is 38.659

so the angle is 38.7 to the nearest tenth.
