Proportions in similar triangles

Mathematics
1 answer:
Svetradugi [14.3K]3 years ago
4 0

Answer:

x = 4

Step-by-step explanation:

Given that DE is parallel to AC then DE divides the sides proportionally, so

\frac{BD}{DA} = \frac{BE}{EC} , substitute values

\frac{x+2}{x} = \frac{3}{2} ( cross- multiply )

3x = 2(x + 2) ← distribute

3x = 2x + 4 ( subtract 2x from both sides )

x = 4

probability = favourable outcomes/total outcomes

you need 1 banana, out of 4 and there are total of 6 items so probability will be 4/6

when you take out 1 banana, there are 3 banana left and total of 5 items

so probability of this action will be 3/5

now, next action is taking out another banana.

this is NOT an independent event.

so by we will multiply the probabilities of these events according to rule of products.

so the answer is \frac{4\cdot3}{6\cdot5}=\frac25

or 2×100/5=40%
