A math teacher opened a window company because he loves seeing shapes or geometrical polygons such as rectagles, squares or quadrilaterals in general as well as triangles in his works. Of course, the math teacher is already familiar with these shapes and how to calculate the angles in between.
step by step explanation:
Add 1 to both sides
52x−1+1=12x+1
Simplify
52x=12x+1
Subtract 12x from both sides
52x−12x=12x+1−12x
Simplify
40x=1
Divide both sides by 40
40x40 =140
Simplify
x=140
