Writing assignment week5

51. Closed to tourists since 1990, the leaning tower of pisa in italy leans at an angle of about 84.7 degree. The figure shows that the top is 50 degree. Find the distance, to the nearest tenth of a foot, from the base to the top of the tower.

 c/sinC = b/sinB

b² = a²+ c² - 2ac* cosC

• b² = 160²+140² - 2 x 160 x 140 x cos80°
