Answer:
60.2 m
Step-by-step explanation:
Let x represent the width of the river. The distance from the point across from the tree to the second point is 15 m. The angle from this point to the tree across the river is 76°.
This makes the side opposite the angle x, the width of the river. It also means the 15 m side is adjacent to this angle.
The ratio opposite/adjacent is the ratio for tangent; this gives us the equation
x/15 = tan(76)
Multiply both sides by 15:
15(x/15) = 15(tan(76))
x = 15(tan(76)) ≈ 60.2
In this question , we have to write an arithmetic expression that calculates the average of 18 and 46.
TO find the average, we have to add the numbers and divide by 2.
So here we have to add 18 and 46 and divide by 2, that is

And that's the required algebraic expression .
To convert a percentage to decimal form, you need to divide the number in the percent by 100. In reality, that just looks like moving the decimal point to the left two places.
83% / 100 = 0.83
83% in decimal form is 0.83.
Hope that helped! =)
Answer:
1, 2/2, 3/3, 5/5, etc.
Step-by-step explanation:
4/4 is a whole number because it's four over four. It can be any number that has the same number on top of it, or one.
I hoped this is what you wanted.

Answer:
x>14
Step-by-step explanation:
X-3> 11
Add 3 to each side
X-3+3> 11+3
x > 14
The hole is open at 14 since it is greater than
( it would be closed if it were ≥) The line goes to the right since it is greater than
