Answer:
y=131°
x=53°
Step-by-step explanation:
∠ ABD and ∠ BDC are supplementary.
The sum of the supplementary angles =180 °
thus y-4+x=180...........i
x and 37° are complementary, that is, they add up to 90°
Thus, x=90-37=53°
Using this value in equation 1 we obtain:
y-4°+53° =180°
y= 180°-53°+4°
y=131°
Answer:
$1.20
Step-by-step explanation:
Ratio:
Grams : Kilograms
1 : .001
Multiply both sides by 20 to convert grams to kilograms:
Grams : Kilograms
1 : .001
x20 x20
20 : .02
This means that 20 grams of lead = .02 kilograms of lead
Price:
Cost : Kilogram
$60 : 1
Multiply both sides by .02 to find the price of the lead:
Cost : Kilogram
$60 : 1
x.02 x.02
$1.20 : .02
Therefore, .02 kg of lead costs $1.20.

Answer:
Decagon
Step-by-step explanation:
We can use the general equation to determine the sum of interior angles:
Since we know the sum of interior angles (I.A.) is 1440°, we must figure out n - the number of sides and so:
Since n=10 this means that it is a 10 sided shape meaning it's a decagon.
This is an equilateral triangle,
so all sides are equal,
5x-4=3x
2x=2,
x=2
So
|AC|=5x-4=5*2-4=10-4=6
|AC|=6
