Let the height = x

Base = 2x

Area of triangle = (1/2)*base*height

Area = (1/2)*2x*x = 4 

x² = 4

x = √4

x = 2

Height = 2 km.

PLEASE HELP<br><br><br> Solve.<br><br> 5x+2/2 = 2x - 1<br><br> X = ________ ?
lakkis [162]
5x + 2/2 = 2x - 1
2/2 is basically 1 so
5x + 1 = 2x - 1
isolate the variable
5x + 1 = 2x - 1
      -1          -1
5x = 2x -2
-2x   -2x
3x = -2
solve
3x/3=-2/3
x=-2/3

KengaRu [80]

Answer:

<h2>0i</h2>

The imaginary number has form:

<em>a + bi</em>

<em>a</em><em> - real part</em>

<em>bi</em><em> - imaginary part</em>

<em>i</em><em> - imaginary unit (i = √-1)</em>

patriot [66]

Answer:

35 cm

Step-by-step explanation:

volume of cylinder = πr²h

πr²h = 1058.75π

Divide both sides by π.

r²h = 1058.75 cm³

r = 5.5 cm

Substitute r² with (5.5 cm)².

(5.5 cm)²h = 1058.75 cm³

h = 1058.75/30.25 cm

h = 35 cm
