When finding the angles in a triangle you need to know that all triangles have a total of 180 degrees worth of the three angles. With this information you can set up an equation where 90+32+8y-6=180.
Now you just have to simplify the equation by adding 90 and 32. This gets you 122. Now subtract 6 to get 116. Now you should have 116+8y=180.
Next subtract 116 from 180 to get 64. The equation is now 8y=64. Now by doing some simple algebra you have simplified the equation and all you have to do is divide 64 by 8 and you get y.
The answer would be D) 52,165 + 49,872 since the key word in the question was total, that would call for addition and total to ''sum'' it all up would mean addition again and D would be your answer.
