Answer:
(0,-3)
Step-by-step explanation:
To form a linear pair means that when added, they equal 180 degrees.
but if they have equal measures....180/2 = 90...then they would both equal 90 degrees.....and 90 degrees is a right angle.
So ABC and CBD are both right angles
Just remember that
1meter=100 cm
81.66m=81.66*100=8166 cm
