Step-by-step explanation:
All triangles must have angles that add up to the same amount of degrees, so if the two triangles share one exact point, it is assumed that those angles would be the same.

64%
Step-by-step explanation:
The percentage of variation in the dependent variable explained by the estimated regression is calculated with the coefficient of correlation as follows:
First, square the coefficient of correlation: 0.8^2 = 0.64
And then, multiply this result by 100, so that, it is expressed as a percentage: 0.64*100 = 64%
Step-by-step explanation:
it will be x in terms of y or vice versa
