What is the equation of the horizontal line through (-7,-3)?​
sweet-ann [11.9K]

m=y2-y1

m=(-7,-3)

m=-10

y-y1=m(x-y2)

y-(-7)=10(x-(-3)

y+7=10x+30

y=10x+30-7

y=10x+37

respuesta y=10x+37

Can I get some help here?
andrew-mc [135]

Answer:

AB, CB, AC

Step-by-step explanation:

All the angles in a triangle added up equal 180 degrees

Start by finding the measure of angle A

A + 86 + 27 = 180

A + 113= 180

A = 67 degrees

Now order them

86 is greater than 67 and 27 so B is the greatest

27 is less than 86 and 67 so C is the smallest

67 is less than 86 but greater than 27 so A is in the middle

Now for the sides..

AB is opposite angle C so it's the shortest

CB is opposite angle A so it's in the middle

AC is opposite angle B so it's the longest

I hope this helps!!!
