Answer:
Step-by-step explanation:
Two angles are Complementary when they add up to 90°.
Therefore
Slope point form for the equation of a straight line
=m(x-x1) + y1
y= 5/4 (x-8) +5
y= 5/4x - 10 + 5
y= 5/4x - 5
I tried every combination. there seems to be something wrong with the informations you gave.
the second equation contains errors, and none of these 4 points can be solutions to the first equation alone
You would count on.
I hope i am right
B. 81 square units
Area for a square is length times width. In this case, both are 9 so 9 x 9 = 81
