Answer:
C, 12,800
Step-by-step explanation:
40 x 320 = 12,800
Answer:
slope(m)=rise/run
m=100/5
m=20
y=mx+c where c is the y intercept, y intercept here is 0
so, y=20x is correct
As these triangle has two proportional sides lengths (20/5 = 4 = 12/3), and this pair of sides confines two congruent angles (<P = <S), so these two triangles are similar...
and the postulate for this is: Side-Angle-Side (SAS)
choice: D
