3 0

Answer:

x = 2\sqrt{5}

Step-by-step explanation:

2² + 4² = x²

4 + 16 = x²

\sqrt{x^2} = \sqrt{20}

x = \sqrt{2^2} × \sqrt{5}

x = 2\sqrt{5}

Use the relationships in the diagram below to write an equation and solve for X
Firlakuza [10]
A. x^2 + b^2 = c^2  
    x^2 + 18^2 = 30^2
    x^2 + 324 = 900
    x^2 = 900 - 324
    x^2 = 576
    x = sqrt 576
    x = 24 <===

b. (2x + 20) + (2x) + (x) + (3x + 20) = 360
     8x + 40 = 360
     8x = 360 - 40
     8x = 320
     x = 320/8
     x = 40

2x + 20 = 2(40) + 20 = 80 + 20 = 100
2x = 2(40) = 80
3x + 20 = 3(40) + 20 = 120 + 20 = 140

What percent is represented by the shaded area?<br><br>flip your phone sideways​
vfiekz [6]

there are two pieces, both divided in 10 equal segments.

so each piece is 10/10, or namely 1 whole.

two pieces, 10/10 each, is 20/10 for the whole thing, but there are only 11 shaded, so if we take 20 to be the 100%, what is 11 off of it in percentage?

\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 20&100\\ 11&x \end{array}\implies \cfrac{20}{11}=\cfrac{100}{x}\implies 20x=1100\\\\\\ x=\cfrac{1100}{20}\implies x=55
