perpendicular: They are perpendicular due to the fact they cross at right angles to each other. Another true instance of perpendicular lines we will see in nature is a football field. All four corners of a football field are perpendicular to every other.

In the trapezoid attached there aren't any perpendicular sides. A and B are both obtuse angles in this diagram, and C and D are both acute angles. However, now not all trapezoids appear like this. ... Definition B: A trapezoid is any quadrilateral with at the least one pair of parallel sides.

K^2+5k-6=0 quadratic formula

s2008m [1.1K]

I hope this helps you

1.k^2+5k-6=0

a=1

b=5

c= -6

disctirminant =b^2-4ac

disctirminant =5^2-4.1. (-6)

disctirminant =49

x1= -(5)+ square root of 49/2.1

x1=-5+7/2

x1=1

x2= -5- square root of 49/2.1

x2= -5-7/2

x2= -6
