Step-by-step explanation:
according to pythagoras theorem
Hypotenuse2 = Perpendicular2 + Base2
c2 = a2 + b2
therefore,
x2 = (4)2 + (4)2
x2 = 16 + 16
x2 = 32
x = √32
hence, x = 4√2
The first one
if u need an explanation comment
True! If you have any 3 segments, it could form a triangle, just not a right triangle.
From the explanation below,
a= -10 and b= -4
