If 2A:3B=5:6 and 3B:2C=36:15, then find A:C

A : C = 2 : 1

Step-by-step explanation:

Expressing the ratios in fractional form

= ( cross- multiply )

15B = 12A ( divide both sides by 15 )

B = A = A

and

= ( cross- multiply )

45B = 72C ( substitute B = A )

45 × A = 72C

36A = 72C ( divide both sides by C )

36 × = 72 ( divide both sides by 36 )

= =

Then

A : C = 2 : 1

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
