Sum of interior angles in a pentagon=540°
148+112+2x+2x+10+90=540
360+4x=540
4x=540-360
4x=180
x=180/4
x=45°
Answer:
x = 17
Step-by-step explanation:
x + x + 8 = 42 because x = boys and x + 8 = girls
2x = 34 because 2x = 42 - 8
x = 17
i hope this helps! you don't need the 2x = 42 - 8 to be an equation ;)
20/35 gallons per hour
(20/35) * 47 = around 27 gallons in 47 hours
