Answer:
cos α = 8/17
Apply Pythagoras theorem for triangle ,
Let get unknown side of triangle is y
17^2 = 8^2 + y^2
17^2 - 8^2 = y^2
225 = y^2
y = sqrt(225)
y = 15
tan α = 15/8

Step-by-step explanation:
The other when put into that formula seem too big or disproportionate to each other
BUT IM NOT SURE.

Answer:
135°
Step-by-step explanation:
Angle 8 and the one marked 45° are a linear pair, so are supplementary.
angle 8 = 180° -45°
angle 8 = 135°
Answer:
Step-by-step explanation:
Previous concepts
The mean absolute deviation or MAD "is the average of the absolute deviations or the positive difference of the given data and that certain value (generally central values)". And is given by this formula:
Solution to the problem
Assuming the info from the picture. So then the data is this one:
66,69,70,70,71,72,72,72,73,73,74,75,75,75
So the first step is find the mean for the dataset with the following formula:
And if we replace the values we got:
And now we need to subtract for each value the mean like this:
Data 
66 5.929
69 2.929
70 1.929
70 1.929
71 0.929
72 0.0714
72 0.0714
72 0.0714
73 1.0714
73 1.0714
74 2.0714
75 3.0714
75 3.0714
75 3.0714
Now we need to add the deviations and divide by the the number of data values and we got:
Answer: The answer is option D, leads to additional melting.
Step-by-step explanation:
As stated in the phrases that came before it, soot-covered snow has a darker surface, which melts more quickly since it heats up. In contrast, a whiter, soot-free surface would reflect heat. In contrast to ice and snow, which can reflect heat, uncovered land and water are likewise dark and incapable of doing so. Only option D accurately describes the self-reinforcing cycle that the phrases before it already suggest. Choices A, B, and C are inaccurate because the data they each present contradicts the statement made earlier that the soot's "outcome" is "a self-reinforcing cycle."
Here's a similar question with answer about self-reinforcing cycle:
