How does the measure of the pink inscribed angle compare with the measure of the blue intercepted arc? How do you know?
Goryan [66]

Answer:

The pink angle is half the angle subtended by the blue arc.

Step-by-step explanation:

Given

See attachment for circle

Required

Compare the pink angle to the blue arc

Let the pink angle be x and the angle subtended by the blue arc be y.

So, we have:

x \to angle at circumference

y \to angle subtended by arc

The relationship between x and y is:

y =2x

Make x the subject

x = \frac{1}{2}y

Write the equation of the line that passes through the points (2,0) and (1,-2)
Darya [45]

Answer:

y

=

Explanation:

First, we need to determine the slope of the line. The formula for determining the slope of a line is:

m

=

y

−

y

−

x

where

m

is the slope and the x and y terms are for the points:

(

x

1

,

y

1

)

and

(

x

2

,

y

2

)

For this problem the slope is:

Now, selecting one of the points we can use the point slope formula to find the equation.

The point slope formula is:

y

Substituting one of our points gives:

y
