a. csc = 15/12
sec = 15/9
b. csc = 15/12
sec = 12/15
c. csc = 9/15
sec = 12/15
d. csc = 9/12
sec = 9/15
a = 9 ; b = 12 ; c = ?
Pythagorean theorem: a</span>² + b² = c²
9² + 12² = c²
81 + 144 = c²
225 = c²
√225 = √c²
<span>15 = c
CSC = cosecant function = hypotenuse/opposite = 15/12
SEC = secant function = hypotenuse/adjacent = 15/9
Choice A: </span><span>csc = 15/12 sec = 15/9 </span>
how many times does 5 go into 78
78/5
it goes 15 times with 3 left over (15*5 = 75 75+3 = 78)
15 3/5 ft
Answer:
x=1
Step-by-step explanation:
3x+9 = 12
Subtract 9 from each side
3x+9-9=12-9
3x = 3
Divide by 3
3x/3 = 3/3
x=1
