Answer:

Yes, it is a right triangle.

Step-by-step explanation:

a^2+b^2=c^2

The longest side is the hypotenuse so c^2 would be 90.

72^2+54^2=90^2

72 and 54 can be either a or b.

Solve for all exponents: 5184+2916=8100.

That equation is true, so the triangle is a right triangle.

Find the value of b/2a+b, when a=5 and b=-2

Murrr4er [49]

Answer:

$-\frac{1}{4}$ or -0.25

Step-by-step explanation:

$\frac{b}{2a+b}$

Plug in a=5 and b=-2

$\frac{-2}{2(5)+(-2)}$ =

$\frac{-2}{10-2}$ =

$\frac{-2}{8}$ =

$-\frac{1}{4}$ or -0.25

Name a career in which one would have to use the phythagorean theorem.Give an example of when and how it would be used.Please wr

DanielleElmas [232]

Answer:

The careers that use Pythagoras theorem are mentioned below.

Step-by-step explanation:

The Pythagoras theorem states that the sum of squares of the two sides of right angled triangle is equal to the square of the length of the hypotenuse.

Let a, b and c be the sides of a right triangle where c is the length of the hypotenuse.Then

$a^{2}+b^{2}=c^{2}$

Pythagoras theorem is used in daily life situations.

A surveyor looks through a telescope toward a measuring stick a fixed distance away, so that the telescope's line of sight and the measuring stick form a right angle.

It is also used to calculate the steepness of slopes and mountains.

Please help hggggggggggh

Answer:

The first blank is: 26

The second blank is: 17

The third blank is: 31 - n

Step-by-step explanation:

So basically each row should add up to 31. So for every number they give you (doesn't matter which color ball), you need to subtract it from 31.

That's why for the first blank, 31 - 5 is 26

second blank, 31 - 14 is 17

and so on....

so the resulting function would be 31 - n

n being a random number that is given to you
