Question

2. In Fig. 8.13, find tan P-cot R.​

Answer 1

Step-by-step explanation:

I think you are asking the value of QR

THEN ACCORDING TO PYTHAGOREAN THEOREM

${(pr)}^{2} = ( {pq)}^{2} + ( {qr)}^{2} \\ {13}^{2} = {12}^{2} + ( {qr)}^{2} \\ ( {qr)}^{2} = {13}^{2} - {12}^{2} \\ ( {qr)}^{2} = 25 \\ qr = \sqrt{25} = 5 \\ qr = 5$
