To find the height of the Kingda Ka roller coaster, you can add the height of the Thunder Dolphin roller coaster to the difference in height:
\[ \text{Height of Kingda Ka} = \text{Height of Thunder Dolphin} + \text{Difference in height} \] \[ \text{Height of Kingda Ka} = 80 \text{ meters} + 59 \text{ meters} = 139 \text{ meters} \]
Therefore, the Kingda Ka roller coaster is 139 meters high.
