Answer:
A = -5/4
Step-by-step explanation:
Slope = rise/run
The line is negative, so the slope will be negative too.
Given the two points, the vertical count is 5 while the horizontal count is 4.
Since slope = rise/run, and the line is negative, the slope is -5/4
I think it would be a also but im not good at math

Answer:
147.5 km and 64.4 km
Step-by-step explanation:
a=120 km
b=70 km
β=28 degrees (
∘)
b^2=(a^2)+(c^2)−2ac*cosβ
70^2
=(120^2
)+(c^2)−2⋅ 120⋅ c⋅ cos(28∘ )
(c^2
) −211.907c+9500=0
note p, q, and r are replacement variables in the Pythagorean theorem since a, b, and c are already in use
p=1;q=−211.907;r=9500
D=(q^2
