It is a numerical coefficient
Answer:
No, it doesn't matter which point is (x1, y1), and (x2, y2), because you will still end up with the same answer when solved. Also, the slope is the change in the y-values over the change of the x-values.
M/_A= 120°
m/_B=30°
m/_C= 100°
sum of all the angles=120+30+100 = 250°
Step-by-step explanation:
Base = 16.9
height = 10.4
Area = ½b×h
A = ½(16.9×10.4)
A = ½(175.76)
Area = 175.76/2
A = 87.88ft²
