Answer is c.
t = 0.5(d+h)
multiply both sides by 2 to cancel out the 0.5.
2t = d+h
2t - d = h
It’s um um.......y......e......a.......h. Yeah
For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut point with the "y" axis
We have, according to the data provided, that the line is of the form:

That means that the slope is -1.

Answer:
the answer is 82° because if u added 45+53+82 it would come out to be 180° which is the overall degrees of a triangle.
