Answer:
(8)(21) = 12x
Step-by-step explanation:
(8)(12) = 21x
(8)(21) = 12x
(12)(8) = 12x
(12)(21) = 8x
Opposite : Adjacent
12 in : 21 in
Opposite : Adjacent
8 in : x in
Equate both ratios to solve for x
12 : 21 = 8 : x
12 / 21 = 8 / x
Cross product
(12)(x) = (21)(8)
12x = 168
x = 168 / 12
= 14
x = 14
