HELP DUE SOON! x = ?? degrees

Answer:

Step-by-step explanation:

Tricky. Very neat.

You are missing the minor arcAC and you need it, but don't fret. It can be found.

The formula for this is x = 1/2(Major Arc(235) - Minor Arc(see below) )

The minor arc is the supplement of x.

The minor arc is also equal to the the central angle

So the minor arc is 180 - x

x = 1/2 (235 - (180 - x) ) Remove the inside brackets

x = 1/2 (55 + x ) Remove the remaining brackets

x = 1/2 *55 + 1/2x Subtract 1/2x from both sides

1/2 x = 27.5 Multiply both sides by 2

x = 55

What's an equation that the passes through (-6,4) and is parallel to y=1/2x+8

deff fn [24]

By definition, if two lines share the same gradient, they are said to be parallel. So, we know for this equation, it must have a gradient of 1/2.

Now, since the point (-6, 4) passes through the line, we know it must satisfy the equation. Since we have a gradient/slope and a point, we can use the point-gradient form:

$y - y_1 = \frac{1}{2}(x - x_1)$ , where $(x_1, y_1)$ represents the points being passed through.

$y - 4 = \frac{1}{2}(x + 6)$
$2y - 8 = x + 6$
$2y = x + 14$
$y = \frac{1}{2}x + 7$
