For 4(3x-1) = 24 -> 3x-1 = 6 -> x = 7/3
For 12x-1 = 24 -> x = 12/25
Apparently, the solution is not the same.
The number 80% is greater than 7/9.
Answer:
A. 90 degrees. The diagonals of a kite are always perpendicular
B. 36 degrees. This longer diagonal of a kite bisects the angle.
C. 54 degrees. The interior angles of a triangle always add up to 180 degrees, so in triangle KHB you can do 180 - 90 - 36 = 54 degrees.
The answer is D because black model A1 are the least wanted
