Answer:
Triangle ACD is similar to triangle RST
Step-by-step explanation:
In triangle ACD
In triangle RST
In triangle ACD
By triangle angles sum property
Substitute the values
Angle A=Angle R
Angle C=Angle S
Therefore, triangle ACD is similar to triangle RST
Reason:By AA similarity postulate
We're going to be using combination since this question is asking how many different combinations of 10 people can be selected from a set of 23.
We would only use permutation if the order of the people in the committee mattered, which it seems it doesn't.
Formula for combination:
Where represents the number of objects/people in the set and
represents the number of objects/people being chosen from the set
There are 23 people in the set and 10 people being chosen from the set
Usually I would prefer solving such fractions by hand instead of a calculator, but factorials can result in large numbers and there is too much multiplication. Using a calculator, we get
Thus, there are 1,144,066 different 10 person committees that can be selected from a pool of 23 people. Let me know if you need any clarifications, thanks!

Answer:
<h2>The answer is - 7</h2>Step-by-step explanation:
The slope of a line given two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
So the slope is
We have the final answer as
<h3>- 7</h3>Hope this helps you
