I know this may be wrong but I think key word think It is c.
Answer:
Hello
your answer is going to be I, 1 
Step-by-step explanation:
Triangle Area = .5 * base * height
48 = .5 * (x +4) * x
48 = (.5x + 2) * x
48 = .5x^2 + 2x
.5x^2 + 2x -48 = 0
x = 8
base = 12
(-11,-3) (-6,7)
7+3/-6+11= 10/-5
Slope is -2
Since the legs are the same length, we know that the remaining two angles must be the same.
120+2x=180
2x=60
x=30
Final answer: x=30 degrees
