Answer:
C: They add up to 180 degrees, because they are a pair of supplementary angles
Step-by-step explanation:
<1 and <2 add up to 180 degrees, so they are supplementary angles.
Complementary angles add up to 90 degrees.
Step-by-step explanation:
floor = 12*10= 120 sq ft
rug = r² = 9 Пr2
120-9π = 91.74 sq ft
36/60, now reduce.
9/15, reduce more
3/5, so 3.5 of the students chosen at random used a calculator for computation.
