Answer:
11 yrs 
Step-by-step explanation:
Mean = sum of ages/number of ages 
Let the age of the seventh girl be A
Given the addition of the age of the seventh girl will make the mean of the ages be 13,
So,
13 = 17+8+12+15+15+13+A/7
Add up the ages 
13 = 80 + A /7
Cross multiply 
80 + A = 13 x 7
80 + A = 91
Subtract 80 from both sides to isolate A
80 - 80 + A = 91 - 80
A = 11
The age of the seventh girl is 11
 
        
             
        
        
        
Answer:
132
Step-by-step explanation:
<em>Theorem:</em>
<em>The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.</em>
x = 60° + 72°
x = 132°
