But how does that translate into differences between the equations for B and C why is c the correct answer please explain cause I need help

Step-by-step explanation:

Two non vertical lines having slopes of m1 and m2 are perpendicular,if and only if m1*m2= -1

the given equation is y=1/6x+3 and it's slope is 1/6

so,m1*m2= -1

1/6*m2= -1

m2= -6

the equation of alone contains point (-2,8) is

y-8= -6(x--2)

y-8= -6(x+2)

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
