Since they are congruent, then $\angle SRV=\angle VTS$

anonymous · Answer

What's the difference? with RSV=TVS    SRV=VTS

watchmath · Answer

For an angle $\angle SRV$ and $\angle RSV$ are differen. The first one is $\angle R$ and the second one is $\angle S$

anonymous · Answer

And so what do I have to do to solve this question? I don't get it...

watchmath · Answer

Look at the angle $\angle R$ and $\angle T$. If they are the same, then what is the value of $x$

anonymous · Answer

2x+3 = 40...

anonymous · Answer

And that's how I got 21.5...

watchmath · Answer

Try to plug in 21.5 into the x and see if it satisfies the equation that you just wrote
