Answer:
C.
Step-by-step explanation:
......................
They are perpendicular because they both meet at (5.5,-2.5)
The triangle is acute. Since all triangles have 180 degrees, you can find the third angle by subtracting the sum of the other angles from 180.
180 - (25 + 87) = third angle
180 - 112 = third angle
68 = third angle
Since all three angles are less than 90 degrees, it is an acute triangle.
Parallel means lines that never meet, and perpendicular are lines that meet at right angles.
