The ratios of sides in a 30°-60°-90° triangle are such that the hypotenuse (AB) is double the length of the shortest side (AC). In your triangle, AC is the hypotenuse of similar triangle ACD, which has AD as its shortest side.
Then
... (1/2)×(AD+54) = AC
... (1/2)×AC = AD
Together, these tell you
... AD = (1/4)(AD +54)
... 3×AD = 54
... AD = 18

Answer:
Line that passes through the points (-6,5) and (-2,7) is,
y=x/2+8, slope is 1/2
line that passes through the points (4,2) and (6,6) is,
y=2x-6, slope is 2
so, there is no relationship between those two lines,
intersection point is (28/3,38/3)
