C option is more reliable for measurement.
Answer:
Step-by-step explanation:
The diagram of the right angle triangle is shown in the attached photo.
From the given right angle triangle,
AC represents the hypotenuse of the right angle triangle.
With m∠32 as the reference angle,
BC represents the adjacent side of the right angle triangle.
AB represents the opposite side of the right angle triangle.
To determine BC, we would apply
the Sine trigonometric ratio which is expressed as
Sin θ= opposite side/hypotenuse. Therefore, the expression used to find BC is
Sin 32 = BC/9
BC = 9Sin32
Answer:
32 kilowatt-hours.
Step-by-step explanation:
The energy usages per day (in kilowatt-hours) of houses on Hamlet Avenue are listed below:
30, 23, 38, 36, 33.
Therefore, the mean energy usage per day of the houses of Hamlet Avenue will be
= 
= 32 kilowatt-hours.
The mean of n numbers is given by,
. (Answer)
What I did was distribution property
4h-12=52
Now you subtract 12 by both side
4h-12=52
-12 -12
4h=40
Divide 4 by both sides
h=10
