Answer:

Ratio: 3:2

LN = 18

Step-by-step explanation:

"similar" means that all the angles are the same and the sides were all increased by the same proportion.

Thus, we know that MN/YZ = LM/XY = NL/ZX

First, we need to find the ratio. To do this, we write MN/YZ as a fraction, and simplify.

MN/YZ = 15/10 = 3/2

(If you want, you can double check this using LM nd XY. 8 * 3/2 = 12, so this is correct)

To find the missing side, we simply multiply XZ by 3/2.

12 * 3/2 = 18, so LN = 18.

Leona [35]

Answer:

60

Step-by-step explanation:

Divide the number of questions answered correctly by his percentage

51 / 85 = 0.6

Now multiply that answer by 100 to see how many questions are on the quiz

0.6 x 100 = 60

Check your work by dividing that number by the number he answered correctly

51 / 60 = 0.85
