The value of the missing segment AB is 4 units
Step-by-step explanation:
A 30,60,90 triangle , is a special right triangle that always contains degree angles 30°, 60° and 90°. It has its side length values which are consistent with one another such when the hypotenuse value is 2 units, the base length is 1 unit and the height is √3 units in relation to the Pythagoras theorem.
In this case, right-triangle CDB has a base angles 60° and 90°.Here the hypotenuse BC=2 units, this will mean the base length DB = 1 unit and the height DC is √3 units. So finding AD, you have CD =√3 and angle CAD =30°, applying the tangent of an angle formula;
tan Ф°=opposite length/adjacent length
tan 30°=√3/AD
AD= √3 /tan 30°
AD= 3 units
Missing segments AB=AD+DB
AB=3+1=4

The emissions per capita measurement is a better because it shows the number of people divided by the emissions.
<h3>What is the difference between total emissions and emissions per capita?</h3>
The emissions per capita show the emissions per each citizen or inhabitant, while the total emissions show only the emissions of the country.
<h3>Which one is better?</h3>
The per capita gauge is better because whether a country is polluting more or not depends on how much each citizen pollutes. This information is useful to create laws that reduce pollution.

Answer:
Chet has 14 baseball cards.
Step-by-step explanation:
Ren has 27 cards, which is 13 more than what Chet has. So you subtract. 27-13=14.
Answer:
Height = 8 cm
Step-by-step explanation:
Volume of cylinder = π×r²×h
288π = π × 36 × h
(Divide both sides by π)
288 = 36 × h
(Divide 288 by 36)
8 = h
You do both of those multiplied by each other
