Answer:
From the laws of angels, the sum of the two opposite interior angles equals the exterior angle. Therefore, from the figure above and going by the law,
Explanation:
48 + (x - 5) = ( 4x - 8)
now solving the equation linearly
48 + x - 5 = 4x - 8
collecting like terms and solve,
48 - 5 + 8= 4x-x
51 = 3x
now divide both side by the coefficient of x which is
X =
