Check the picture below.
make sure your calculator is in Degree mode.
35 + 58 = 93, since all angles in a triangle are equal to 180 you can do 180 -93 to get the third angle, which is 87. Since x is in an exterior angle, 87+x =180. From there its simple. Subtract 87 on each side and you get x = 93.
