The range of the data is 12
Answer:
The length of the unknown side x is 4 cm
Step-by-step explanation:
we know that
The perimeter of a polygon is equal to the sum of its length sides
Remember that
1 cm=10 mm
In this problem we have
AB=45 mm ------> convert to cm -----> AB=45/10=4.5 cm
BC=10 cm 4 mm -----> convert to cm -----> BC=10+4/10=10.4 cm
CD=5 cm 6 mm -----> convert to cm -----> CD=5+6/10=5.6 cm
DE=35 mm ------> convert to cm -----> DE=35/10=3.5 cm
EA=x cm
P=280 mm ------> convert to cm -----> P=280/10=28 cm
The perimeter of the irregular polygon is equal to
P=AB+BC+CD+DE+EA
substitute the values
28=4.5+10.4+5.6+3.5+x
28=24+x
x=28-24
x=4 cm
Answer:
55°
Step-by-step explanation:
y+x=180°
25°+30°+x=180°
25°+30°=y
y=55°

That'd be : 28.8 . I hope this helps. This is it step by step.
60/x=100/48
<span>(60/x)*x=(100/48)*x </span>
<span>60=2.08333333333*x
</span>(2.08333333333) to get x
<span>60/2.08333333333=x </span>
<span>28.8=x </span>
<span>x=28.8</span>
Answer:
Tan(x) = 1/
We know that Tan 30 = 1/
Therefore, x = 30 degrees
