Answer:
hello : sin(θ) = 4/25
Step-by-step explanation:
you know : cos²(θ) + sin²(θ) =1 and : cos(θ) = - 3/5
(-3/5)² + sin²(θ) =1
9/25 + sin²(θ) =1
sin²(θ) =1 -9/25
sin²(θ) = 16/25
sin(θ) = 4/25 or sin(θ) = - 4/25
in quadrant 2 : sin(θ) > 0
so : sin(θ) = 4/25
Answer:
54 cents
Step-by-step explanation:
first, subtract the pencil box from the total
2.46- .30= 2.16
that means the 4 markers cost 2.16

2.16÷4= .54
54 cents per marker
49 = 77% × x

49/.77 = x
63.64 = x
49 is 77% of 63.64
