In ▵PQR, PR is extended through point R to point S, m

x = 10

Step-by-step explanation:

Here, we are tasked with calculating the value of x.

To do this, we need the picture of the wordings given in the question.

please check the attachment for a pictorial representation.

Now the theorem to use is that , the exterior angle of a triangle is equals the sum of the two opposite interior angle.

Thus, mathematically;

3x + 11 + 3x + 15 = 10x -14

6x + 26 = 10x -14

10x-6x = 26 + 14

4x = 40

x = 40/4

x = 10

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,

step-by-step explanation:

by good luck mark me as brainliest

have a nice day
