# Wxy is a Right Triangle

EstateName.com – Wxy is a Right Triangle

Correct Answer is TRUE .i.e., ΔWXY is a right angled triangleStep-by-step explanation:Given: All Sides of ΔWXY .i.e., WX = √34 , XY = √17 and WY = √17To check : If ΔWXY is right angle or notWe 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 = 34XY² + WY² = (√17)² + (√17)²                  = 17 + 17                  = 34Since, WX² = XY² + WY²⇒ ΔWXY is a right angled triangleTherefore, Correct Answer is TRUE

The Factor Theorem says (x – a) is a factor of function p(x) if p(a)=0so check for p(-2)= -2^4 +3(-2)^3 + 4(-2)^2 – 8= 16 – 24 +16 -8= 0so (x + 2) is a factor
