First of all, observe that all fractions exist as long as b is not zero.
Multiply both numerator and denominator of the first fraction by 3:

Now all fractions have the same denominator. Under the assumption that b is not zero, multiply both sides by 3b:

Subtract 3b from both sides:

Subtract 2 from both sides:

Divide both sides by 2:

Answer:
Step-by-step explanation:
using sine formula

Answer:
10/25
Step-by-step explanation:
2/5 = x/25
We need to multiply the bottom by 5 to get to 25
5*5 = 25
What we to the bottom, we do the the top
2/5 * 5/5 = 10/25
