3. Look at the picture.
We have the right angle triangle. We know the sum of measures of angles in triangle is equal 180°. Therefore:


4.
Look at the picture.
Use Pythagorean theorem:



5.
TRUE: 1; 2; 4
6.
We find a slope of the line OP:

We have:

Now, we must find the slope of the line perpendicular to the line OP.
We know:

therefore

So. We have the answer! :)
y b g
/ \ / \ / \
h t h t h t
soooo 6 outcomes
Answer: 90
Step-by-step explanation:
set: {1, 2, 3, 4, 5, 6, 7} = 7 numbers | 3 even
no element may be used more than once in a number = distinct elements
and the number must be even = must finish with a even number.
This way, we should start with the last number, which we have 3 possibilities.
Since we have 7 numbers in total, we have 6 options for the first one and then 5 options for the second one.
So, we have 6.5.3 = 90
