Angle sum theorem ??

Mathematics
1 answer:
lianna [129]2 years ago

Answer:

x = 30°

Step-by-step explanation:

Hello!

The sum of angles in a triangle is 180°. Please, please, remember this, as it will help you along the road in geometry, and is one of the basic rules in triangle theorems.

Assuming that the altitude of the triangle and the bottom ray is perpendicular, the angle next to the 60° angle is 90° or a right angle.

So, taking the left triangle (as both triangles are the same):

  • 60° + 90° + x° = 180°
  • x° = 30°

The value of x is 30°

This can be confirmed by looking at the big triangle, with the base angles of 60°.

Using the same angle rule:

  • 60° + 60° + x° + x° = 180°
  • 2x° = 60°
  • x° = 30°

The value of x is 30°

The following data summarizes results from 889 pedestrian deaths that were caused by accidents. If one of the pedestrian deaths
pickupchik [31]

Answer:

P(A or B) = 0.291 +0.159 -0.0562=0.3938

Step-by-step explanation:

Previous concepts

The total probability rule is "used to find the probability of an event, A, when you don’t know enough about A’s probabilities to calculate it directly. Instead, you take a related event, B, and use that to calculate the probability for A".

Solution to the problem

The data given:

                                                             Pedestrian

                                       Intoxicated                       Not intoxicated     Total          

Intoxicated                           50                                        91                    141

Not intoxicated                    209                                     539                 748

Total                                     259                                      630                889

The rows on this case are associated to the tyep of Driver.

Let's define the following events:

A =Pedestrian was intoxicated

B= Driver was intoxicated

And we can find the probabilities for the events A and B like this with the info given:

P(A) = \frac{50+209}{889}=0.291

P(B) = \frac{50+91}{889}=0.159

We can find also the probaility that pedestrian was intoxicated AND driver was ​intoxicated, like this:

P(A and B) = \frac{50}{889}=0.0562

Because the intersection for the events A and B is 50 and the grand total is 889.

Now we can use the total rule of probability given by this:

P(A or B) = P(A) +P(B) -P(A and B)

And since w ehave everything to replace we got:

P(A or B) = 0.291 +0.159 -0.0562=0.3938
