Answer:

53

Step-by-step explanation:

Sum of interior angles of a pentagon = 540°

Arte-miy333 [17]

Answer:

30% of the pages are arithmetic, or 108 pages

50% are on algebra = 180 pages

360 x .5 = 180

20% are on geometry = 72 pages

360 x .2 = 72

30% are on arithmetic = 108

180 + 72 + 108 = 360 pages

50% + 20% + 30% = 100%
