Help! Please help me find the measure of x, the missing angle shown below -

Answer:
x=21.8
Step-by-step explanation:
The angles are complementary, and add to 90 degrees. We know this because of the little square in the corner.
x+68.2=90
Solve for x by isolating it. To do this , subtract 68.2 from both sides
x+68.2-68.2=90-68.2
x=21.8
Answer:
21.8
Step-by-step explanation:
basically what you're looking at is a right angle (the square) which is 90 degrees and part of it is 68.2 and the other is x.
This can be written as the equation 68.2 + x = 90.
Subtract 68.2 from both sides to get x = 21.8;
and there you go! That's your answer! Hope that helped a little bit :)
