Answer:
~15 meters away
Step-by-step explanation:
c^2 = a^2+b^2
c^2 = 10^2+11^2
c^2 = 100+121
c^2 = 221
c = 
c = ~15
Left side goes up 5 right side goes up 7
The rate of change between 5,15 is 10
The answer to your question i think is b
B) 35
the formula is .5(outer angle - inner angle) = .5(100-30)=.5*70=35
