Answer: 
Step-by-step explanation:
In order to find the value of "x", it is important to remember that:
We can identify in the figure that:
Then:
Solving for AB:
Now, since there are 360° in a circle, we know that:
Then we can substitute 
into 
and solve for "x". This is:
Answer:
HGD: 117
FDG: 180
Step-by-step explanation:
14-6y=44
-14 Both sides
-6y=30
÷-6 both sides
Y=-5
Answer:
f ) x+72=90(complementary angle)
x= 90-72
x=18
g )x+77=90
x=90-77
x=13
plz give me thanks
Instead of adding 6 three times, you can multiply 6 by 3 and get 18, the same answer.
Similarly,
6 + 6 + 6 + 6 + 6 + 6 + 6 = 6 × 7 = 42
