What is the measure of n?

Mathematics
1 answer:
Snowcat [4.5K]3 years ago

Given:

A figure of a right triangle whose altitude divides the opposite in two segments of 8 and 4 units.

The measure of the altitude is n.

To find:

The value of n.

Solution:

According to the altitude on hypotenuse theorem, the altitude on the hypotenuse of a right triangle is geometric mean of two segments of the hypotenuse.

Let the altitude h divides the hypotenuse in two parts with measure a and b, then

\dfrac{h}{a}=\dfrac{b}{a}

h^2=ab

h=\sqrt{ab}             [Because side length cannot be negative]

In the given figure, the altitude is n and it divides the hypotenuse in two segments of 8 units and 4 units.

Using altitude on hypotenuse theorem, we get

\dfrac{n}{8}=\dfrac{4}{n}

n^2=4\times 8

n^2=32

n=\sqrt{32}

Therefore, the measure of altitude is n=\sqrt{32} units.

52,908 round to the nearest hundred.
IrinaVladis [17]

The hundredth is the 3rd number after the decimal place (so the 9). Look at the number before it and if it is 5 or above then round it to the next hundredth. In this case it is only a zero so we don't change the 9 just substitute it 0's. Therefore the answer is 52,900.

If you need further help let me know, hope this helped you.

Estimate the square root of 83 to the nearest whole number.
sleet_krkn [62]
Nothing can go into 83 so of you square root it you will get a decimal so the nearest whole number You would get is 9 because 9*9=81 and that's the closet that you will get to 83
