the Answer would be the Length of BC = 24 units. Since AB = AC you will get that the two are equal. Use this t solve for x.
M>5=m>4
m>5 and m>7 are on line then m>5+m>7=180
by substituting
m>4+37=180
m>4=143
m>2=m>7=37
m>4=m>8
m<3+m>5=180
Answer:
B
Step-by-step explanation:
Slope:

This eliminates answer options C and D
If you plug either set of coordinates into equation B then you will know that it works because both sides will end up equal to each other
Answer:
