Answer:
sum of interior angle of a triangle is 180 degree 
so,
3x +7 + 2x+7 +3x+6 = 180 
8x + 20 = 180 
8x = 180 - 20 
8x = 160 
x = 160/ 8
x = 20

Given that, Two tanks are similar in shape. The capacity of the tanks are 1,000,000 litres and 512, 000 liters respectively.Find the height of the smallest tank if the larger is 300cm tall?
 Assume that, the tanks are rectangular in shapes and differ only on their heights. The volume of the larger tank is 
V1 = l × w × h1 while the volume of the smaller tank is V2 = l ×w × h2. The ratios of the capacities is 

Solving for the height of the smaller tank h2


1000000 × h2 = 51200 × 300 cm
h2 = (51200 × 300 cm) /1000000
h2 = 15.36 cm
