Split 33 into two numbers that when added up are 33.
So 12 to 21, which when divided by 3, are 4 to 7.
Since all straight lines have an angle of 180 degrees if the exterior angle is equal to 113 degrees than you just subtract 113 from 180 which will equal 67.
First lets work out the length of the top side which joins the points (-1,7) and (-5,5):-
this = sqrt ( (7-5)^2 + (-1 - (-5)^2 )
= sqrt (4 + 16)
= sqrt 20
Now find length of the longer side which is distance between the points (-1,7) and (4, -3)
this is sqrt ( (-1 - 4)^2 + (7 - -3)^2)
= sqrt 125
Area of the rectangle = sqrt 20 * sqrt 125
= sqrt 2500
= 50 units^2 Answer
C because the degree is 45
