If you consider the logarithm base 3 of both sides, you have

You can use a rule of logarithms that allow you to turn exponents into multiplicative factors:

So the equation becomes

Now, by definition, you have

So, you have

So, the equation becomes

Answer:
20° and 70°
Step-by-step explanation:
Complementary angles sum up to 90°.
The angle = x
Its complement = x + 50
x + x + 50 = 90
2x = 40
x° = 20°
20+50=70
AB = x
BC = 3x
AC = 20 inches = AB + BC
Let's plug our values into the equation above.
20 inches = x + 3x
Combine like terms
20 inches = 4x
Divide both sides by 4
5 = x
AB = x = 5 inches
BC = 3x = 3(5) = 15 inches
