Answer:
85+(5x-10)=11x+3 (sum of two non-adjacent interior angle is equal to exterior angle )
75+5x=11x+3
75-3=11x-5x
6x=72
x=72/6
x=12

Answer:
q = 6
Step-by-step explanation:
3/5 = q/10
10 ÷ 5 = 2
3 × 2 = 6
3/5 = 6/10
 
        
             
        
        
        
If arc =AB is equal to arcCD then line AB should equa lineCD
        
             
        
        
        
The answer is h = 2A/(b1 + b2). 
In order to find this, use all the methods for solving typically used in these types of equations. See the below example. 
A = 1/2(b1 + b2)h ---> Multiply both sides by 2. 
2A = (b1 + b2)h -----> Divide both sides by (b1 + b2)
2A/(b1 + b2) = h
