Answer:
AEB =305° as stated below
Step-by-step explanation:
AEB is the larger area starting A to EB and missing out the small AB area
EC = 180° = supplementary we label 87° angle to P.
P+ BCD = 87, + 38 = 125°
ABCD = 180°
180 - BCD = 180-125°
AB = 55°
Therefore AEB = 360-55=305°

Answer: 23.9
Step-by-step explanation:
1. First, you must calculate the mean, as following:
2. Now, you should substract the means obtained to every single number of the set and then square it. Add all of them:
3. The mean of this is:
4. The square root of this result is:
5. To the nearest tenth, the result is: 23.9

Answer:
24
Step-by-step explanation:
Corresponding lengths are proportional. The ratio of the full length to the given part is ...
(30 +x)/30 = 45/25
1 +x/30 = 1 +4/5 . . . perform the division
x/30 = 4/5 . . . . . . . . subtract 1
x = 30(4/5) = 24
The missing side length is 24.
Answer:
y=4/3x+4
Step-by-step explanation:
y-y1=m(x-x1)
y-(-8)=4/3(x-(-9))
y+8=4/3(x+9)
y=4/3x+36/3-8
y=4/3x+12-8
y=4/3x+4
