Answer:

I think the whole Line would be 16

Step-by-step explanation:

You have to use the Pythagorean Theorem.

so do 6^2 + x^2 = 10^2

then solve and you get x^2 = 64 which means x=8

then since CE and ED are the same and congruent lines ED will also be 8 so you add the 8 up and get 16.

sorry if I'm wrong

7. A kite in the shape of a square with a diagonal 32 cm and an isosceles triangle of base 8 cm and sides 6 cm each is to be mad

grin007 [14]

Answer:

Step-by-step explanation:

diagonal = 32 cm

Area of square = $\dfrac{d^{2}}{2}$

$=\dfrac{32*32}{2}\\\\=512 \ cm^{2}$

Diagonal separate the square into two equal triangles.

Area of upper triangle that is shaded black = area of lower triangle = 512/2

= 256 cm²

Isosceles triangle:

a = 6 cm ; b = 6 cm c = 8cm

$s = \dfrac{a+b+c}{2}\\\\=\dfrac{6+6+8}{2}\\\\=\dfrac{20}{2}\\\\=10\\\\s-a = 10 - 6 = 4 \ cm\\\\s-b = 10-6 = 4 \ cm\\\\c - c = 10 - 8 = 2 \ cm\\\\Area = \sqrt{s*(s-a)(s-b)(s-c)}\\\\=\sqrt{10*4*4*2}\\\\=\sqrt{2 * 2 * 4 * 4 * 5}\\\\=4*2\sqrt{5}\\\\=8\sqrt{5}\\\\=8*2.24\\\\=17.92 \ cm^{2}$

Area of black shade paper = 256 + 17.92 = 273.92 cm²

Area of white shade paper = 256 cm²

Area of the isosceles triangle = s(s-a)(s-b)(s-c)

A particular Chevy averages 20 miles per gallon in stop-and-go urban environments but averages about 28 miles per gallon on the

irga5000 [103]

784=20x+28y
30 = x + y
x=urban
y=highways

so isolate a variable then substitute

30 - x = y

substitute:

784 = 20x + 28(30-x)

784 = 20x + 840 - 28x

784-840 = 20x - 28x +840 -840

-56/8 = -8x/8

7 = x

substitute back in

30 = x + y

30 = 7 + y

30-7 = 7 - 7 + y

y = 23
