Answer:
-50
Step-by-step explanation:
Dan's elevation is -50 feet below sea level. If Lola is at an elevation of 670 feet and Dan is 720 feet below her, you need to subtract; 670 - 720. This would get you to -50 feet which is Dan's elevation. Hope this helps!

x = 104
The exterior angle is equal to the sum of the opposite interior angles

24+x-24 =128 -24
x =104
