Answer:

Astronomers.

Step-by-step explanation:

In many, many ways we can use geometry in astronomy. One of the most or important example is that when astronomers find the distance between the different celestial bodies and they also find the tilt of any planet they uses geometry .

And in this field other uses of geometry when planets orbiting around the sun or satellites orbiting around there planets astronomers uses geometry to find the speed and velocity of the planets.

If the hypotenuse of a 45°-45°-90° triangle is 13, what is the length of one of the legs?

stiv31 [10]

Answer:

9.19

Step-by-step explanation:

Using Law of sines to find other two lengths:

a/sinA=b/sinB

let a be length of side unknown and b be hypotenuse then sinB=sin90 and sinA=sin45

a/sin45=13/sin90

a=13sin45

a=13(0.707)

=9.19

As the given triangle is isosceles hence the length of other two legs will be same i.e 9.19 !

Is √6/8. rational or irrational?

Ipatiy [6.2K]

<h2>Answer:</h2>

The number is irrational.

<h2>Step-by-step explanation:</h2>

<h3>1. Convert to decimal.</h3>

$\sqrt{\frac{6}{8} } =\sqrt{0.75} =0.8660254038...$

<h3>2. Conclude.</h3>

Since this number shows to have infinite decimal figures, it cannot be represented as the ratio of 2 integers. Hence, the number is irrational.

-------------------------------------------------------------------------------------------------------

Note. In case the number expressed in the question was $\frac{\sqrt{6} }{8}$ , the answer would still be irrational, for the same reasons explained above.
