Simply remember PEMDAS:
P = Parentheses
E = Exponents
M = Multiplication
D = Division
A = Addition
S = Subtraction
You perform these actions from left to right.
However in this case it is not possible for it to equal 60.
There are several ways to solve this, but the law of sines is probably the easiest...
Law of Sines: sina/A=sinb/B=sinc/C for any triangle...in this case we can say:
sin48/x=sin90/55
xsin90=55sin48
x=55sin48/sin90
x≈40.873 (to nearest one-thousandth, not sure which precision you needed)
Answer:
9
Step-by-step explanation:
How more feet is the outer perimeter of the walkway than the perimeter of the pool is 48 ft
Since 6ft is the width of walkaway
Hence:
Let increase in width be 12
Let increase in length be 12
Now let determine How many
more feet is the outer perimeter of the walkway than the perimeter of the pool
Outer perimeter Number of feets = 2×(12+12)
Outer perimeter Number of feets = 2×24
Outer perimeter Number of feets = 48 ft
Inconclusion How more feet is the outer perimeter of the walkway than the perimeter of the pool is 48 ft
