We shall use a negative sign for an elevation below sea level, and a positive sign for an elevation above sea level.
Given:
Elevation of city A = -96 ft (below sea level)
Elevation of city C = -24 ft (below sea level)
Let x = elevation of city D.
Part A.
Because the elevation of city D is 1/4 of the elevation of city C, therefore
x = (1/4)*(-24)
Part B.
Because 24/4 = 6, therefore
x = -6 ft.
Answer:
The elevation of city D is 6 feet below sea level.
The answer is negative because the elevation is below sea level.
Answer:
Step-by-step explanation:
As we know that,
Area of isosceles triangle= 1/2 *b*h
we have a=10 and other side = hypotenuse=b=13 cm
Now e have formula to find h,
h=
now putt the values ,
we get,
h=
h=
<h2>
h=12 cm height of isosceles triangle ,</h2>
Area = 1/2 * b*h
Area=1/2*13*12
<h2>
Area=S=60
</h2>
