How do I answer this Question? It’s phythagoras theorem!

zhuklara [117]

Answer:

C = 11.18 D= 20

Step-by-step explanation:

Let's start with C

Square root both areas of the squares

$\sqrt{25} =5$

$\sqrt{100}=10$

Then use the Pythagoras Theorem: $a^{2} +b^{2} =c^{2}$

$10^{2} +5^{2} =125$

$\sqrt{125} =11.18033989$ = C

Moving on to D

Square root both areas of the squares

$\sqrt{841} =29$

$\sqrt{441} =21$

29 is the hypotenuse, we are trying to find the other leg, so:

$29^{2} -21^{2} =400$

$\sqrt{400} =20$ = D

Find the coordinates of the circumcenter for ∆DEF with coordinates D(1,3) E (8,3) and F(1,-5).

NemiM [27]

Let the coordinates of the circumcentre O of the triangle DEF be (x, y). Circumcentre of a triangle is equidistant from each of the vertices.

1. Distance OD=distance OE, then:

$(x-1)^2+(y-3)^2=(x-8)^2+(y-3)^2$ .

2. Distance OD=distance OE, then:

$(x-1)^2+(y-3)^2=(x-1)^2+(y+5)^2$ .

Solve the system:

$\left\{\begin{array}{l} (x-1)^2+(y-3)^2=(x-8)^2+(y-3)^2 \\ (x-1)^2+(y-3)^2=(x-1)^2+(y+5)^2 \end{array}\right.$ ,

$\left\{\begin{array}{l} x^2-2x+1+y^2-6y+9=x^2-16x+64+y^2-6y+9 \\ x^2-2x+1+y^2-6y+9=x^2-2x+1+y^2+10y+25 \end{array}\right.$ ,

$\left\{\begin{array}{l} 14x=63 \\ -16y=16 \end{array}\right.$ .

Then

$x=\dfrac{63}{14} =\dfrac{9}{2} =4.5,\\ \\ y=-1$ .

Answer: the coordinates of the circumcenter for ∆DEF are x=4.5, y=-1.
