Answer:
s measures 33° and t measures 57°.
Step-by-step explanation:
Since the two angles s and t are complementary, this implies that:
We are given that t is 9 less than twice s. Hence:
We can substitute this into the first equation:
Solve for s. Combine like terms:
Adding 9 to both sides yields:
And dividing both sides by 3 gives us that:
Returning to our second equation, we have:
So:
So, s measures 33° and t measures 57°.
