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
Answer: x=3, p/2,-p/2
Step-by-step explanation:
it's hard to explain, so let me know if you really want me to explain.
so we have 3 folks painting 4 walls, now each one of them works for 32 minutes
person 1............. 32 mins
person 2............. 32 mins
person 3............. 32 mins
for a total of 32+32+32 = <u>96 minutes worth of work</u>. That's for 4 walls, how many minutes worth is just 1 wall?
96 ÷ 4 = 24 mins.
so to paint a wall, it takes 24 mins of work worth.
so then, to paint 7 walls, that'd be 7 * 24 = 168 minutes worth of work.
what about for 4 folks doing it? How many times does 4 go into 168? 168 ÷ 4 = 42 mins.
