Answer:
Tower A: 1258
Tower B: 404
Explanation:
Since we don't know the height of tower B, let's call that x.
So, the height of tower A is x+854.
and the equation for both towers together is x+x+854=1662
or 2x+854=1662
Now subtract 854 from both sides then divide by 2 to get x=404.
So, Tower B is 404 feet tall and Tower A (404+854) is 1258 feet tall.
