I think I know what you mean but I don't know what is meant by base, if you tell me I might be able to work it out.
I may be wrong but the last one seems right
Answer:
firstly We see that the ratios of corresponding sides are equal. Therefore, the sides are proportional, and the two polygons are similar.
...
If all of them are equal, then the polygons are similar:
Side 1: 4/8 = 1/2.
Side 2: 1/2.
Side 3: 5/10 = 1/2.
Side 4: 6/12 = 1/2.
Step-by-step explanation:
Answer:
x = 8, y = 4
Step-by-step explanation:
x = 3y-4
2x - 8 = 2y
x - 4 = y
x = y + 4
substitute top equation to this equation
3y-4 = y+4
2y = 8
y = 4
now substitute this into second equation
x = y + 4
x = 8
check answer with first equation
x = 3y-4
8 = 3(4) - 4
8 = 8; correct
