Find the measure of angle b
2 answers:
Ok, so the measurement of all the angles together has to equal 360 degrees. So the angle directly across from 100 is also 100 (because they are vertical angles) which equals 200. That means you have 160 degrees left to figure out. Since you have to find the measurement of the other TWO angles, just divide 160 in half and then you have the measurement for angle b.
The answer is 80 degrees.
Sorry if this is a long answer. I hope it helps though.

I will show the way.
Step-by-step explanation:
r is the correlation coefficient
To find SSxy
SSxy= ∑- ∑
To find SSxx
SSxy= ∑-
∑x
/n
To find SSyy
SSxy= ∑-
∑y
/n
if your r is near +1, it shows strong positive correlation. Y is proportional to X.
And if it nears -1, it would show strong negative correlation. Y is inversely proportional to X.
