The value of x is 20.

Solution:

Sides of one triangle are 2x – 4 and 39.

Sides of another triangle are x + 6 and 24.

<u>Property of similar triangle:</u>

<em>If two triangles are similar then their corresponding angles are congruent and the corresponding sides are in the same ratio.</em>

$$\frac{2x-4}{24} =\frac{39}{x+6}$

Do cross multiplication.

$(2x-4)(x+6)=39\times 24$

$2x^2+12x-4x-24=936$

$2x^2+8x-24-936=0$

$2x^2+8x-960=0$

Divide by 2 on each of the term.

$x^2+4x-480=0$

Solve using quadratic equation.

$(x-20)(x+24)=0$

$(x-20)=0, \ (x+24)=0$

$x = 20, \ x = -24$

Ignore the negative term, because if you substitute this you will get a negative terms only. But length of sides cannot be in negative measures.

Therefore x = 20.

billy is creating a circular garden divided into 8 equal sections. The diameter of the garden is 12 feet. what is the area, in s

xxTIMURxx [149]

Area=πr^2

find the area then divide by 8

we know that diameter=2radius or diameter/2=radius so
12=diameter
12/2=radius=6
subsitute
area=π(6)^2
area=36π
divide 36π by 8
36π/8=18π/4=9π/2π=4.5π
area of one section is 4.5π square feet or if we aprox pito 3.14159 then we get
4.5(3.14159)=area=14.1372 square feet or 14.14 square feet
