In the diagram shown, line m is parallel to line n . justine says that ∠3 ∠ 3 and ∠7 ∠ 7 are supplementary angles. is she correct? why or why not?
a. no, because ∠3∠3 is an interior angle and ∠7∠7 is an exterior angle.
b. no, because they are not a linear pair.
c. yes, because ∠3∠3 and ∠8∠8 are congruent corresponding angles, and ∠7∠7 and ∠8∠8 are a linear pair.
d. yes, because ∠3∠3 is acute and ∠7∠7
is obtuse.

The correct answer is C.

Because by looking at the diagram you can see that angles 7 and 8 are intersected

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
