What should Stacy do to explain the relationship between an exterior angle and the interior angles in a triangle? A. Stacy should first show that m∠1+m∠3=m∠2+m∠4. Then she should subtract to show that m∠1=m∠2 and m∠3=m∠4.

B. Stacy should first show that m∠4=m∠3. Then, since m∠1+m∠2+m∠3=180∘, she should substitute to show m∠1+m∠2+m∠4=180∘.

C. Stacy should first show that m∠4+m∠2=m∠1+m∠2+m∠3. Then she should subtract to show that m∠4=m∠1+m∠3.

D. Stacy should first show that m∠4=m∠2. Then, since m∠1+m∠2+m∠3=180∘, she should substitute to show m∠1+m∠4+m∠3=180∘.

y -5 = (-1/4)(x + 8)

step-by-step explanation:

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
