By definition of supplementary angles, m∠1 + m∠2 = (a) and m∠2 + m∠3 = (b). Then, m∠1 + m∠2 = m∠2 + m∠3 by the (c). Subtract m∠2 from each side. You get m∠1 = (d), or ∠1 ≅ (e).

i dont know the answer but here's a picture of a dog

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.

contact me if you have any questions you are welcome.

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
