Step-by-step explanation:
simplify the second expression
I don't quite understand what you are asking . The properties ? Like addition property or transitive ?
Answer: It looks like you are missing the question here. Most of the time in this type of questions, we are looking for the 3rd angle.
Let's assume that you need the 3rd angle.
There are 180 degrees in a triangle. We know 2 of the angles, so by subtracting them from 180 we can find the 3rd angle.
180 - 45 - 60 = 75
Angle C is 75 degrees. In the similar triangle Angle R is also 75 degrees because the corresponding angles are congruent.
Answer:
25 miles a day
Step-by-step explanation:
75 divided by 3 is 25
Answer:
The best estimate of the correlation coefficient is 0.9 from the given data.
Step-by-step explanation:
From the scatter plot, the line of best fit will have a positive slope.
So, the correlation coefficient , 
is greater than 0.
so, ≠ - 0.9
Also, there is a deviation from absolute linearity.
So, ≠ 1
Again from the scatter plot it is closer to linearity than further.
Hence, ≠ 0.3 .
So = 0.9
