Answer:

82 degrees

Step-by-step explanation:

Measure of arc ABC = 86*2 = 172 degrees.

Measure of arc DC = 360 - (145+172) = 360-317 = 43 degrees.

Measure of arc BCD = 121+43 = 164 degrees.

Measure of angle A = 164/2 = 82 degrees

Write (2 4) and (6 16) in the form y=mx+b
Lena [83]

Answer:

y = 3x-2

Step-by-step explanation:

We can find the slope using the formula

m = (y2-y1)/(x2-x1)

  = (16-4)/(6-2)

  =12/4

 =3

We then use the point slope form of a line

y-y1= m(x-x1)

y-4 = 3(x-2)

Distribute the 3

y-4= 3x-6

Add 4 to each side

y-4+4 = 3x-6+4

y = 3x-2

This is in slope intercept form

Perform the indicated operation. Simplify the result in factored form. ((x - y)/ (x^2 - 1)) * ((x - 1)/(x^2 - y^2))
Scilla [17]

Answer:

The answer to your question is            \frac{1}{(x + 1)(x + y)}            

Step-by-step explanation:

Real operation

                      \frac{x - y}{x^{2} - 1} \frac{x - 1}{x^{2} - y^{2}}

Process

1.- Factor the denominators

                     \frac{x - y}{(x + 1)(x - 1)} \frac{x - 1}{(x + y)(x - y)}

2.- Simplify like terms

Cancel (x - y) and (x - 1) because they are in numerator and the denominator

                    \frac{1}{(x + 1)(x + y)}            This is the answer or you can expand

3.- Expand

                   \frac{1}{x^{2} + xy + x + y^{2}}
