Answer:
The first transit on one side of the trench is 18 ft higher than the other side of the trench. The transit is set at 4.5 above ground, therefore the transit lens is 18' + 4.5' = 22.5' above the location on the other side of the trench. The angle of depression is the angle formed by the horizontal and the line of sight to the other side and it is given as 31°. This forms a right angle triangle with height of 22.5' and an interior angle of 31°, Then
tan( 31°) = Height / base, with the base representing the width of the trench
base = Height / tan(31°) = 22.5' / tan(31°) = 37.45' is the width of the trench
1. 0
2. 32.6
3. 326
4. 3260
considering i’m not the best at maths, can someone check these for me?

Step-by-step explanation:
<em>Given: Side lengths of a right triangle 3,4 and 5 units.
</em>
<em>
To draw: A right triangle with the given side length.
</em>
<em>
Solution:
</em>
<em>
We know, in a right angle triangle hypotenuse is the longest side and satisfying Pythagoras theorem.
</em>
<em>
From the given side length,
</em>
<em>
Hypotenuse = 5 unit
</em>
<em>
We can take any of the base and perpendicular.
</em>
<em>
Let, Base = 3 unit
</em>
<em>
Perpendicular = 4 unit.
</em>
<em>
It a right-angle triangle with a hypotenuse 5 unit.
</em>
<em>
Now we draw a right angle triangle taking in the first 3 base and 4 perpendicular and second 3 perpendicular and 4 bases.</em>
Hey there.
If the decimal point is .500 and up, we will be rounding up. If it is .499 and lower, we will be rounding down.
Now let’s look at the numbers.
2.500 g can be rounded up, so we’ll make that 3.000 g.
5.000 g is going to stay the same, since the decimal point is .000
2.268 g will be rounded down, making it 2.000 g
5.670 will be rounded up and will become 6.000 g
And finally, 11.340 g will be rounded down to 11.000 g.
Hope this helps!
3u³ - 4u² - 9u + 12
u²(3u) - u²(4) - 3(3u) + 3(4)
u²(3u - 4) - 3(3u - 4)
(u² - 3)(3u - 4)
