1. No

2. Yes

3. No

4. Yes

Step-by-step explanation:

Plug in values for the unknowns into bother expressions to see if the give the same answer.

I don't really know how to do this but the best thing I can say is to replace those variables with a number and then put it in a calculator. Make sure each variable has a different number.

so for the first one, I made s as 2 and t as 3. I got 18 for the first one and 6 on the other one so they're clearly not equal.

good luck!

e) none of the above because the measure of angle cba is 101°
