Hi there!
\boxed{\angle A = 75^o, \angle B = 105^o}

Let there be two angles, ∠A and ∠B, that are supplementary to each other. Therefore:

∠A + ∠B = 180°

We can assign ∠B to be the greater angle. Assume ∠A has a measure of x°.

∠A = x°

∠B = x° + 30°

The sum is equal to 180°, so:

x° + (x° + 30°) = 180°

Solve for x°.

2x° + 30° = 180°

2x° = 150°

x° = 75°

Thus, ∠A = 75°.

Since ∠B is 30°, greater:
∠B = 75° + 30° = 105°.

Which expression is equivalent to log3 c/9?
stepladder [879]
Hello!

There is an existing logarithmic property that states that log \frac{M}{N} is equal to log M-logN.

Following that property, we can tell that log \frac{c}{9} would be equal to log(c)-log(9).

ANSWER: log(c)-log(9) (third option)
