True or false? triangle wxy is a right triangle

Correct Answer is TRUE .i.e., ΔWXY is a right angled triangle

Step-by-step explanation:

Given: All Sides of ΔWXY .i.e., WX = √34 , XY = √17 and WY = √17

To check : If ΔWXY is right angle or not

We use the result which states that if in a triangle square of largest side is equal to sum of squares of other two side then triangle is right angles.

So, WX² = (√34)² = 34

XY² + WY² = (√17)² + (√17)²

                 = 17 + 17

                 = 34

Since, WX² = XY² + WY²

⇒ ΔWXY is a right angled triangle

Therefore, Correct Answer is TRUE

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
