There are 18 people waiting for the train. Eight-ninths of them have an umbrella. How many people waiting for the train have an
Pie

Answer:

Step-by-step explanation:

Ok, so there are 18 people. If 8/9 have umbrellas, how many have umbrellas?

There is a simple solution to this.

First, lets find out how much people is 1/9

We can do this by dividing 18 by 9 to get 2

So 1/9 of the group is 2 people.

Now you can use this to find 8/9 by multiplying 2 by 8

This gives you the total of 16

Another way you could do this was take the answer from the first step and subtract that from the 18

9/9 - 1/9 = 8/9   => 18 - 2 = 16

Hope this helps! =)

The least amount of information needed to establish congruence is; Angles M and M' are congruent, and angles N and N' are congruent.

<h3>What is the least amount of information needed to determine if the two triangles are similar?</h3>

If follows from concept of congruence that two triangles are congruent only if all three angle measures are congruent or all corresponding sides are in the same ratio.

Hence, when angles M, N and M', N' are established as congruent, it follows that the measures are equal respectively.

Ultimately, the measure of angles L and L' are equal and hence, all three angles are congruent in each triangle.

Therefore, the least amount of information needed is; Angles M and M' are congruent, and angles N and N' are congruent.
