In circle B, given isosceles triangle BTX, BA ⟂ WX, and WX = 10, what is the radius of circle B rounded to the nearest whole num
Eva8 [605]

Solution :

We observe that :

$\overline {BA} \perp \overline {WX}$

But BA is the perpendicular.

From the center B and WX is a chord.

Therefore, TW = TX (perpendicular from the centre of a circle to a chord bisects it)

Consider Δ BTX,

∠BTX = 90° (BA ⊥ WX)

BT = XT (Δ BTX is isosceles)

Since the angles opposite to equal sides are equal of a triangle arc are equal.

∠BTX = ∠BXT

But in the triangle,

∠TBX + ∠TXB + ∠BTX = 180°

∠TBX + ∠TBX + 90° = 180°

2 ∠TBX = 90°

∠TBX = 45°

From trigonometry, we get

$\sin \theta =\frac{TX}{BX}$    ...............(1)

WX = 10

i.e., TX + TW = 10

But TX  = TW

     2 TX = 10

         Tx = 5

BX = radius of circle.

∴ $\sin 45^\circ = \frac{5}{BX}$

  $\frac{1}{\sqrt2} = \frac{5}{BX}$

 $BX = 5\sqrt2$

        $=5 \times 1.41$

        = 7

Therefore, the radius of the circle is 7 units.

Y-3=(x+2)^2<br><br> Please explain how you graph this and find the vertex and axis of symmetry
bija089 [108]
Okay so I attatched pictures of my work. I would just graph it by plugging in x-values on either side of the vertex into the equation. For example, the vertex is at (-2,3). So try plugging x=-5 and x=1 into the equation (y=a(x-h)^2 +k).
y=(x+2)^2 +3
y=((1)+2)^2 +3=(3)^2+3= 9+3= 12 
Now you can plot the vertex (-2,3), the point (1,12), and (-5,12). From there just connect the dots and you should get a graph that looks similar to the last picture I attached. Hope this all made sense sorry it was so wordy I just wasn't sure how much you knew or didn't know. So, I thought it would be better to explain it all rather than not enough.
