Answer: It's Congruent but not similar because the shape on top doesn't look like the bottom left.
Step-by-step explanation:
Answer: A = 20
How to Solve:
Just by looking at this problem I can tell that the denominators (9 an 45) are factors of 9. So the second equation is multiplied by 5 from the first equation.
4/9 x 5
4 x 5 = 20
— -—
9 x 5 = 45
So A would be 20.
Another way to solve this would be by multiplying the 1st equations numerator with the second equations denominator:
4 x 45 = 180
Then divide 180 with the 1st equation’s denominator.
180 / 9 = 20
A = 20
