What is the value of s?

The answer to your question is 33°

Step-by-step explanation:

Data

∠1 = 39°

∠2 = 108°

∠3 = ?

Process

To solve this problem, remember that the sum of the internal angles in a triangle equals 180°.

Then,

              ∠1 + ∠2 + ∠3 = 180°

-Substitution

             39° + 108° + ∠3 = 180°

-Solve for ∠3

              ∠3 = 180 - 39 - 108

-Simplification

              ∠3 = 180° - 147°

-Result

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
