Answer:
sin
Step-by-step explanation:
take 34 degree as reference angle
usinf sin rule
sin 34=opposite/hypotenuse
0.55=16/x
x=16/0.55
x=29.09
x=29.1
Answer:
41x/35y
Step-by-step explanation:

Answer:
5 lbs
Step-by-step explanation:
90 - 53.10 = 36.90
She spent $36.90 on coffee. Since it cost $7.38 per pound, we can divide the total cost by 7.38 to figure out how many pounds she bought:
36.90 / 7.38 = 5
Raina bought 5 pounds of coffee.
The answer would be C: 128+8.50x+9.50y+10z.
This is because all of the costs of the different items will add up depending on how much of them the family buys. This is why they all have the corresponding variables next to the prices. The prices of those items will be added on to the initial cost of the 128$ family package, so all of the prices would be added up together to get the total.
the perimeter is the sum of the 3 sides of the triangle, hence
4x + 10x + 12x = 104
26x = 104 ( divide both sides by 26 )
x = 4
thus the sides of the triangle are
4x = 4 × 4 = 16 inches
10x = 10 × 4 = 40 inches
12x = 12 × 4 = 48 inches
As a check
16 + 40 + 48 = 104 inches ← correct
