Answer:
8
Step-by-step explanation:
let the number be n , then
n + 3 = n - 3 ( multiply through by 4 to clear the fraction )
n + 12 = 4n - 12 ( subtract 4n from both sides )
- 3n + 12 = - 12 ( subtract 12 from both sides )
- 3n = - 24 ( divide both sides by - 3 )
n = 8
That is the number is 8
Total coverage = 0.85 x 185,000 = $157,250
Coverage for Loss of Use = 0.25 x 157250 = $39,312.50
For number 11 the third angle would be equal X as the second angle is, since the two sides next to the those angles are congruent. Then you would have to set an equation saying that 2x + 38= 180 and then you can just solve for X
Answer:
Length of the lake is 97.30 m
Step-by-step explanation:
We have given Caleb starts at one end of the lake and walk 95 m
So 
And then he turns at an angle of 60°
So
and then again walk 8 m
So 
We have to fond the total length of the lake , that is d
Total length of the lake is given by 
So length of the lake is 97.30 m
