Answer:
area of traingle=1/2(sin130×AB×AC)
85×3=sin130×AB×AB
255=76×AB²
255/76=AB²
√332.88=AB
AB=18.24
AC=18.24
Step-by-step explanation:
Hope this helps.
Answer: 31.43 meters
Step-by-step explanation:
First find the circumference of the circle.
= π * diameter
= 22/7 * 80
= 251.43 meters
If there are 8 points equally spaced, the distance between the points is:
= 251.43 / 8
= 31.43 meters

Answer:
The 32 electricians will take 1 day and 3 hours to complete the wiring.
Step-by-step explanation:
Since it takes electricians 36 days to wire a new housing subdivision, to determine how many days would 32 electricians take to do the same job the following calculation must be performed:
36/32 = X
1.125 = X
1 = 24
0.125 = X
0.125 x 24 = X
3 = X
Therefore, the 32 electricians will take 1 day and 3 hours to complete the wiring.
