2x+7x=747
9x=747
x=83
83(2) = 166
83(7) = 581
The answer should be B because if she wants to make more than $120 she has to sell more than 8 dozens. The circle isn’t shaded because shaded means “more than or equal to” and since since she wants more than 120 instead of 120 or more the circle is open.
Answer:
sum of interior angle of triangle is 180°
therefore, 81°+37°+X=180°
118°+X =180°
X=180°-118°
X=62°
k+x=180°
k+62°=180°
k=180°-62°
k=118°
hence proved
OR
the sum of 2 interior angle is equal to a exterior angle,so 81°+37°=k
118°=k
