Answer:
70 degrees
Step-by-step explanation:
If you have a calculator you first change the mode to degrees then do shift/2nd cos to get cos^-1 then enter it like this: cos^-1(342/1000)
and you will get your answer 70 degrees
Answer:
0.50
Step-by-step explanation:
The question asks you to apply the classical method of computing probability. In this method, prior events do not interfere in the likelihood of an event happening in the future, instead it states that every possible outcome is equally likely to happen.
In this case there are only two possible outcomes: purchase or not purchase a computer. Therefore, the likelihood that the next customer will purchase a computer is 50% or 0.50.
Answer:

Step-by-step explanation:
Isosceles triangles are a type of triangles in which two of their sides have an identical length. It should be noted that the angles opposite the sides that are the same length are also the same. This means that these triangles not only have two equal sides, but also two equal angles.
You can solve this problem using different methods, I will use pythagorean theorem. First take a look at the picture I attached. As you can see:

And we can find a easily using pythagorean theorem:

Solving for a:


Therefore:
