Answer 1

Answer:

Step-by-step explanation:

Hypotenuse is the side opposite to 90°.

$Sin \ R = \dfrac{opposite \ side \ of \ angle \ R}{Hypotenuse}$

          $= \dfrac{PQ}{PR}\\\\\=\dfrac{36}{60.40}$

$Cos \ P =\dfrac{adjacent \ side \ to \ angle \ P}{hypotenuse}$

           $=\dfrac{PQ}{PR}\\\\\\=\dfrac{36}{60.40}$

$Tan \ R =\dfrac{opposite \ side \ to \ angle \ R}{adjacent \ side \ to \ angle R}$

            $=\dfrac{PQ}{QR}\\\\\\=\dfrac{36}{48.50}$

$Cot \ R = \dfrac{adjacent \ side \ of \ angle \ R}{opposite \ side \ of \ angle \ R}$

           $=\dfrac{QR}{PQ}\\\\\\=\dfrac{48.50}{36}$
