Answer:
9
Step-by-step explanation:
similar triangles.
that means there is one common factor to transform the lengths of all lines from one triangle to the other.
it looks to me DF is the longest side in DEF, and that would make it associated to BC of ABC.
so, the factor is then
BC = DF×f
24 = 12×f
=> f = 2
so, EF then is associated to AC.
AC = EF × f
18 = EF × 2
EF = 18/2 = 9
Unknown factor is known as the factor that is not understood and not know(you have no idea what the value is)
quotient is the answer of two different numbers called dividend and divisor being divided with each other
<h3>Answer:</h3>
28inch^2
<h3>Step-by-step solution:</h3>
Rectangle:
<em>[</em><em>L</em><em>e</em><em>n</em><em>g</em><em>t</em><em>h</em><em> </em><em>x</em><em> </em><em>B</em><em>r</em><em>e</em><em>a</em><em>d</em><em>t</em><em>h</em><em>]</em>
5 + 3 = 8inch
8 x 2.5 = 20inch^2
Right Triangle:
<em>[</em><em>1</em><em>/</em><em>2</em><em> </em><em>x</em><em> </em><em>B</em><em>a</em><em>s</em><em>e</em><em> </em><em>x</em><em> </em><em>H</em><em>e</em><em>i</em><em>g</em><em>h</em><em>t</em><em>]</em>
1/2 x 5 x 2 = 1/2 x 10
= 5inch^2
Left Triangle:
<em>[</em><em>1</em><em>/</em><em>2</em><em> </em><em>x</em><em> </em><em>B</em><em>a</em><em>s</em><em>e</em><em> </em><em>x</em><em> </em><em>H</em><em>e</em><em>i</em><em>g</em><em>h</em><em>t</em><em>]</em>
1/2 x 3 x 2 = 1/2 x 6
= 3inch^2
20 + 5 + 3 = <u>2</u><u>8</u><u>i</u><u>n</u><u>c</u><u>h</u><u>^</u><u>2</u>
180/3x then you get you answer
