To answer this question you must know that there is a theorem called the "Two secants angle theorem", which establishes that the measure of an angle formed when two secants intersecting  outside the circle is equal to 1/2 the difference of the two intercepted arcs.
 Therefore, as you can see, the correct answer is the option B): B)1/2 the difference of the intercepted arcs.

Answer:

(B) {\frac{1}{2}} the difference of the intercepted arcs.

Step-by-step explanation:

Two secants angle theorem: Two secants theorem states  that the measure of an angle formed when two secants intersects outside the circle is always equal to  {\frac{1}{2}} the difference of the two intercepted arcs.

Therefore, from the theorem of two secants angle, The measure of an angle formed by two secants intersecting outside the circle equals {\frac{1}{2}} the difference of the intercepted arcs.

Hence, option B is correct.

Find a third number so that three numbers form a right triangle.<br><br>9,41​
expeople1 [14]

Answer:

40

Step-by-step explanation:

a^2+b^2=c^2

therefore c^2-b^2=a^2

41x41=1681

9x9=81

1681-81=1600

Sqrt1600=40

Describe in words the region of R3 reperesented by the equations or inequalities x2+y2=4,z=-1
Roman55 [17]

Answer:

It represents a circle of radius 2, centered in the origin of the plane xy and transversal to the z-axis in z=-1.

Step-by-step explanation:

The first thing to notice is that

x^2+y^2=2^2

<u>represents a circle of radius 2</u>, with its center in the origin of a plane xy, of cartesians coordinates.

Starting from here, we have to put the coordinate z, to complete the space R³. <em>Then, the cirlce will "live" into the plane xy, where z=-1</em>.

Finally, we have that this region is a circle of radius 2, centered in the origin of the plane xy, and transversal to z=-1.

Write an equation of that passes through the points (-2,-3,) and (2,5)
MAVERICK [17]

Answer:

y = 2x + 1

Step-by-step explanation:

Find the slope

( -2 , -3) ( 2 , 5)

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

x1= -2

y1 = -3

x2 = 2

y2 = 5

m = 5 - (-3)/ ( 2 - (-2)

m = (5 + 3) / ( 2 + 2)

= 8/4

= 2

m = 2

Using the equation of a line

y = mx + c

y - intercept point y

m - slope of the line

x - intercept point x

c - intercept

Substitute m into the equation

y = 2x + c

Substitute any of the two points given into the equation

( 2 ,5 )

x - 2

y - 5

y = 2x + c

5 = 2(2) + c.

5 = 4 + c

c = 5 - 4

c = 1

The equation of the line

y = 2x + 1
