Answer:

Angle CDE equals 155 degrees :D

Step-by-step explanation:

parallel lines

since the left angle is 57, angle BAE is also 57

180-57=123

right angle=90

115+90+123+57=385

540-385=155

thus, angle CDE equals 155 degrees

If your constant of proportionality is 10inches in one minute how do you find how many minutes it takes for a snail to move 85 i
pshichka [43]

Answer:

8.5 min

Step-by-step explanation:

Here, distance = rate times time.  The rate is 10 in/min, and so

d = (10 in/min)t.

If the snail travels 85 in, then 85 in = (10 in/min)t, and we solve for t as follows:

t = (85 in) / (10 in/min) = 8.5 min
