Answer:
$7.67
Step-by-step explanation:
So if 8 pens cost $4.72, one pen would cost $0.59. 0.59 x 13 will be equal to 7.67.
By definition we have:
sineA = (C.O) / (h)
cosA = (C.A) / (h)
Where,
C.O: opposite leg
C.A: adjacent leg
h: hypotenuse
Substituting values:
sinA = (48) / (50)
cosA = (14) / (50)
Answer:
sineA = (48) / (50)
cosA = (14) / (50)
