Double checking: On the first try I got 113, That turned out to the the wrong answer. I understand how 23 and 67 can be a answer but 77 I can’t seem to do the math for it, so if someone can help me get the right answer, please and thanks.

∠DCE = 67

Step-by-step explanation:

In triangle DCE,

∠DCE + 23 + 90 = 180 (angle sum property)

=> ∠DCE + 113 = 180

=> ∠DCE = 180 - 113

=> ∠DCE = 67

Hope it helps :)

Please mark my answer as the brainliest

0.872

Step-by-step explanation:

The line is increasing.  This means the correlation coefficient will be positive.

This is a fairly good fit; this means we want the larger of the two positive numbers, or 0.872.
