Answer:
140 degree
Step-by-step explanation:
The sum of the interior angle measures in a regular polygon is 1260 degree.
(n-2)*180=1260
180n-360=1260
180n=1260+360
180n=1620
n=1620/180
n=9
Now, evaluate the measure of one of the interior angles of the polygon.
((9-2)*180)/9=140 degree.
Answer:
398.71 ft
Step-by-step explanation:
Length of rebar = 18 inches = 1.5 ft
Elevation = 393.66 ft
Reading of backsight on Benchmark= 7.56 ft
Rod reading = 1.10 ft
<em>First step : determine height of Instrument been used</em>
= elevation + backsight on Benchmark
= 393.66 + 7.56 = 401.22 ft
<em>Elevation of top of rebar </em>
= 401.22 - 1.01 = 400.21 ft
Finally determine the elevation of the top of the pipe
= 400.21 - length of Bar
= 400.21 - 1.5 = 398.71 ft

Answer:
2/5
Step-by-step explanation:
How much of the 5/6 is in 1/3 means there is 3/4 of some number which gives a result of 1/3.
Assuming the unknown number to be x, we can write it as:
(5/6)x = 1/3
Now solving for x, 6 in the denominator of x is multiplied to (1/3):
5x = 6 (1/3)
5x = 2
Divide 2 by 5 to get:
x = 2/5
Therefore, the answer is 2/5.
