As we know that angle of semi circle is 180°.
Here,
FLG = 40°
GLH = ?
HLJ = 60°
FLG + GLH + HLG = 180°
40° + GLH + 60° = 180°
GLH + 100° = 180°
GLH = 180° - 100°
GLH = 80°
Now,
FLH = 40° + 80° = 120°





Step-by-step explanation:

Square both sides of the equation.


Answer:
0.03125 inches 1 hour is the anwser
this also involves the conversion factor
hope this helps!!
I think this might be the answer since (a+b) equals 4, and ab= 3. I'm not sure.
a3 + b3
= (4)3+4(3)
= 12+12
= 24
