Answer:
The correct answer is 24 
Step-by-step explanation:
to solve this you will need to use the pathagreom theorum 
a^{2}+b^{2}=c^{2}
A= one side lenth
B= the secons side lenth 
C= hypotnuse 
It is helpfull to draw out the situation 
you know that the latter is 25 ft, that is your hypotnuse 
you also know that the 7 ft away from the base of the building is one of the side lenths, lets call it side a 
so plug the numbers into the equation 
7^2 + b^2 = 25 ^2 
you leave b^2 alone because that is the side you are trying to find 
now square 7 and 25 but leave b^2 alone 
49 + b^2 = 625 
now subtract 49 from both sides 
b^2 = 576 
now to get rid of the square of b you have to do the opposite and square root both sides removing the square of the B and giving you the answer of..........
B= 24 
Hope this helped!! I tryed to explain it as simpil as possiable 
 
        
                    
             
        
        
        
Answer:
64°
Step-by-step explanation:
Angles in a straight line add up to 180° so 180° - 116° = 64°
 
        
             
        
        
        
13,822 to one significant figure is 10,000
623 to one significant figure is 600
14 to one significant figure is 10
10,000 times 600 = 6,000,000
6,000,000/10 = 600,000
