Answer:
b = 90
Step-by-step explanation:
Sum the interior angles of the pentagon and equate to 540
Starting from the top and going clockwise
b + b + 45 + 90 + 2b - 90 +  b = 540 ← simplify left side
 b = 540 ← simplify left side
 b + 45 = 540 ( multiply through by 2 to clear the fraction )
 b + 45 = 540 ( multiply through by 2 to clear the fraction )
11b + 90 = 1080 ( subtract 90 from both sides )
11b = 990 ( divide both sides by 11 )
b = 90
Thus
b + 45 = 90 + 45 = 135
2b - 90 = 2(90) - 90 = 180 - 90 = 90
 b =
 b =  × 90 = 135
 × 90 = 135
The angle measure from the top clockwise are
90°, 135°, 90°, 90°, 135°
 
        
             
        
        
        
Answer: 5-10g+20h
Step-by-step explanation:
You can rewrite as 5(1-2g+4h). 5x1 equals 5, 5x2g=10g, 5x4h=20h, then you get 5-10g+20h

do parentheses first which gives you 42-4+111 then aubtract to get 38+111 which equals 149
