PLSSSSSSSS HELLPPPPPP.......Which triangle’s unknown side length measures StartRoot 53 EndRoot units?

Orlov [11]

The right answer is Option 2: A right triangle with side length of √47 and hypotenuse of 10.

Step-by-step explanation:

We know that;

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

We will put the unknown length as √53 to check the solution.

Option 1: a = 6 , b = √53 , c = √91

$(6)^2+(\sqrt{53})^2=(\sqrt{91})^2\\36+53=91\\89\neq 91$

Option 2: a=√47, b = √53, c = 10

$(\sqrt{47})^2+(\sqrt{53})^2=(10)^2\\47+53=100\\100=100$

Option 3: a = √19, b=√53, c= √34

$(\sqrt{19})^2+(\sqrt{53})^2=(\sqrt{34})^2\\19+53=34\\72\neq 34$

Option 4: a=√73, b=√53, c=20

$(\sqrt{73})^2+(\sqrt{53})^2=(20)^2\\73+53=400\\126\neq 400$

Option 2 satisfies pythagoras theorem.

Therefore;

The right answer is Option 2: A right triangle with side length of √47 and hypotenuse of 10.

If two variables are directly proportional then their graph is a linear function

Nezavi [6.7K]

It is true that if two variables are directly proportional then their graph is a linear function.

<h3>How to determine the true statement?</h3>

The highlights in the statement are given as:

Two variables
Direct proportion
Linear function

The equation of a directly proportional graph is represented as:

y = kx

Where k represents the constant of variation

The equation y = kx is a linear function and k is the slope

Hence, it is true that if two variables are directly proportional then their graph is a linear function.
