Answer:
9
Step-by-step explanation:
1. First, we need to set up an equation to find the value of x and then the length of EF.
2. We know that DG is equal to 33, so we can add all the three sections it's cut into altogether to get 33. Therefore, we get an equation of:  
 
3. (Solving for x)
Step 1: Simplify both sides of the equation.
Step 2: Add 58 to both sides.
Step 3: Divide both sides by 7.
4. Now that we know x is equal to 13, we can plug that value in for the expression 3x - 30.
Therefore, the length of EF is 9.

When writing a fraction in plain text, parentheses are needed around the entire denominator. The order of operations tells you that a/bc = (a/b)c, not a/(bc).
 
        
             
        
        
        
Answer:
70
Step-by-step explanation:
I would do 40 + 30 = 70
180-70 = 110
110 is the last angle bc all angles add to 180 in a triangle
Then 180 - 110 = 70 for angle 1 because their supplementary 
I don't know if you could just add the 2 inside angles but I would do it this way to be safe until I know for sure.
