Answer:
Step-by-step explanation:
The formula for this is
∠G = 1/2(arcEH - arcHF)
We have angle G (5x - 10) and we have arcEH (195) so we have to solve for x to find the measure of arcEHF so we can add arcEH + arcHF = arcEHF
Filling in the formula with what we have:

which simplifies down a bit to
 which simplifies down a bit more to
 which simplifies down a bit more to
 Multiply both sides by 2 to get rid of the fraction and get:
 Multiply both sides by 2 to get rid of the fraction and get:
2(5x - 10) = 178 - 8x which of course simplifies to
10x - 20 = 178 - 8x. Now add 8x to both sides and at the same time add 20 to both sides to get:
18x = 198 so
x = 11. Now we can find the measure of arcHF:
arcHF is 8x + 17, so arcHF is 8(11) + 17 which is 105°. 
arcEH + arcHF = arcEHF so
195 + 105 = arcEHF so
arcEHF = 300°
 
        
             
        
        
        
Answer:
1/4
Step-by-step explanation:
You can set up ratios or fractions for the matching sides.
A/B
1/4 = 1/4
1.1/ 4/4= 1/4
1.5/6 = 1/4
 
        
                    
             
        
        
        
Hello!
The quotient means dividing
The quotient of 63 and 9 is 63/9
12 more means we add
The expression is 63/9 + 12 or 12 + 63/9
Hope this helps!
