Answer:
$36 left
Step-by-step explanation:
42+37=79
115-79=36
Answer: Choice 1) The sum of the angles A and B are supplementary to angle C
Why is this the answer? Because we'll use facts 2 through 4 to help prove the triangles similar. If fact 2 is true, then fact 3 leads to helping set up the congruent corresponding angles (either A = D or C = E). Fact 4 is true because all angles are congruent to themselves, and this fact is the other angle pair we need to prove the triangles similar.
We don't use fact 1 even though it's a true statement. The fact that A+B+C = 180 isn't really useful to compare across two triangles.
Answer:
B.
Step-by-step explanation:
use distributive property
4*x + 4*3 = 4x+12
AB is 6 because of the definition of a midsegment 1/2(12)
