Question

Triangle RSV is congruent to triangle TVS. Find x.


I got x=21.5 Is it correct??

The diagram is attached

Answer 1

Since they are congruent, then \(\angle SRV=\angle VTS\)

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

2x+3 = 40...

Answer 7

And that's how I got 21.5...

Answer 8

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

Answer 9

oh it doesn't xD

Answer 10

oops I should have subtracted 3

Answer 11

It's 18.5 xDD Thank you for helping

Answer 12

you are welcome :)
