Answer:

109°

Step-by-step explanation:

Consider an isosceles triangle by joining the end points of tye chord to the centre

Base angles of the traingle:

(180 - 142)/2 = 19

The edge of the triangle makes 90° with the circumference

Angle x = 19 + 90 = 109°

Answer:

As shown in picture, the circle is divided into 2 arcs, one of them is 142 deg.

Then the other one A is 360 - 142 = 218 deg (property of sum of all arcs on circle).

As the property of angle created by a tangent line:

x = (1/2) x arc A = (1/2) x 218 = 109 deg

Hope this helps!

Given the equation 4x2 − 8x 20 = 0, what are the values of h and k when the equation is written in vertex form a(x − h)2 k = 0?
Westkost [7]

The vertex form of the given quadratic equation is

4(x-1)^{2} + 16 =0.

According to the given question.

We have a quadratic equation

4x^{2} -8x + 20 = 0

Since, for the standard quadratic form is ax^{2} +bx + c = y, the vertex form of a quadratic equation is y = a(x -h)^{2} + k where (h, k) is the vertex.    

And h and k can be calculated as

h = -b/2a and y = k

So, for the given equation 4x^{2} -8x + 20 =0 the vertex (h, k) is given by

h = -(-8)/2(4) = 8/8 = 1   (X coordinate of vertex)

and,

y =4x^{2} -8x+ 20

substitute x = 1 in the above equation for the value of k

Y = 4(1)(1) - 8(1) + 20

⇒ Y = 4 - 8 + 20

⇒ Y = -4 + 20

⇒ Y = 16

so, k = 16          (Y coordinate of vertex)

Now, substitute the value of a, k and h in y = a(x-h)^{2} + k.

⇒  0 =4(x-1)^{2} + 16

Therefore, the vertex form of the given quadratic equation is

4(x-1)^{2} + 16 =0.
