a) 108°

Answer:

b) 54°

Step-by-step explanation:

a) By arc sum property of a circle.

m\widehat {AEB} + m\widehat {AB} = 360°\\252° + m\widehat {AB} = 360°\\m\widehat {AB} = 360°- 252°\\\huge \red {\boxed {m\widehat {AB} = 108°}} \\

b) In the given figure, DC is tangent to the circle with O at point A and AB is chord or secant. Therefore, by tangent secant theorem:

m\angle BAC = \frac{1}{2} \times m\widehat {AB}\\\\\therefore m\angle BAC = \frac{1}{2} \times 108°\\\\\huge \purple {\boxed {m\angle BAC = 54°}}

68 | 86 | 104 | 122 | 140 | 158 | 176 | 194 | 212 | 230 | 248 | 268

Step-by-step explanation:

Ok so, the top part of the table is probably going to be the number of months. The cost of the video streaming is linear and follows the equation

cost = 18*cost per month + initial cost

or

cost = 18(number of months) + 50

Using  the table which they gave, enter the number of months at the top, and enter the cost at the bottom. I've gaven the answer already. The months go to welve, and the answer goes into the bottom.

Comment on my answer if it doesn't make sense.

Thank You!

Find the equation of the line parallel to y=x-3 that also intersects the points (3,-2)
Reika [66]

Answer:

y = x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = x - 3 ← is in slope- intercept form

with slope m = 1

• Parallel lines have equal slopes, hence

y = x + c ← is the partial equation of the parallel line.

To find c substitute (3, - 2) into the partial equation

- 2 = 3 + c ⇒ c = - 2 - 3 = - 5

y = x - 5 ← equation of parallel line
