3/5 is bigger because 4/7 = 20/35 and 3/5 = 21/35
Step-by-step explanation:
Given
Slope (m) = 4
Point ( -1 , 5)
Now the equation of line is
y - y1 = m ( x - x1)
y - 5 = 4 ( x + 1)
y - 5 = 4x + 4
4x + 4 - y + 5= 0
4x - y + 9 = 0
which is the required equation
Answer:
216
Step-by-step explanation:
We know that the two angles must add up to 180
so
108+x/3=180
solve for x
72=x/3
x=216
