Answer:
x = 53
Step-by-step explanation:
Similar means that the corresponding angles are congruent (the same) - basically what this means is that ∠L ≅ ∠G, ∠M ≅ ∠J, and ∠N ≅ ∠H.
Since we know that the angle measures in a triangle should add up to 180 and we know the measures of ∠L and ∠M already, we can do
180 = 67 + 60 + N
So, N = 180 - (67 + 60) = 180 - 127 = 53.
Since ∠N ≅ ∠H, ∠H = 53.

answer
width = 98 cm
length = 105 cm
set up equations
the perimeter of a rectangle = 2W + 2L
p = 2W + 2L
the perimeter is also 406
406 = 2W + 2L
we know that the length of the rectangle is 7 cm longer than the width so
L = W + 7
substitute equations and solve for width
plug L into p = 2W + 2L to get
406 = 2W + 2(W + 7) distribute the 2 to the terms in the parentheses
406 = 2W + 2W + 14
406 = 4W + 14
392 = 4W
W = 98
substitute equations and solve for length
now that we know the width, we can substitute W in L = W + 7 to find length
L = W + 7
L = 98 + 7
L = 105
final dimensions
width = 98 cm
length = 105 cm
I believe it is 4. I am not 100% sure
Which sampling method divides the population up into sections, randomly selects some of those sections, then chooses all the members from the selected sections to study?
Answer: The above mentioned type of sampling is called cluster sampling.
Cluster sampling is a sampling technique in which the entire population of interest is divided into clusters or groups, then the investigator randomly selects some of these clusters and all the members of these randomly selected clusters are investigated.
