angle 1+angle 2 = 180 degrees
Step-by-step explanation:
when 2 angles are supplementary, they equal 180 degrees when they are added up. Because angles 1 and 2 are supplementary, this means that angle 1 + angle 2 equals 180 degrees.
For this case we can apply the Pythagorean theorem to find "x". Taking the rectangle triangle of base 5 we have:
By definition of power properties we have:
So:
