Two similar pyramids have corresponding dimensions in the ratio 3:5 Find the ratio of their volumes

Step-by-step explanation:

Given

Ratio of corresponding dimensions is in the ratio of

If the two pyramids are similar then the ratio of their volumes is proportional to the cube of their side ratio

i.e.

Thus the ratio of their volumes is

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
