In right triangle PQR , PQ=12 cm and QR=5cm .What is cos R?
Juliette [100K]

Answer:

cosR = \frac{5}{13}

Step-by-step explanation:

assuming the right triangle has ∠ Q = 90° with legs 5 and 12

then this is a 5- 12- 13 right triangle with hypotenuse PR = 13 cm

then

cosR = \frac{adjacent}{hypotenuse} = \frac{QR}{PR} = \frac{5}{13}
