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)<span>1/2 the difference of the intercepted arcs</span>
Angles are undefined terms in plane geometry.
The true statements are:
- <em>4. </em><em>.</em>
- <em>5. </em><em />
- <em>6. </em><em> is an obtuse angle</em>
- <em>7. Its supplement must be an acute angle</em>
- <em>8. See attachment</em>

<u>Question 4</u>
The first statement is represented as:
Supplement of
means that A and B are congruent.
The supplementary of A and B would be the same
The measure of A is then calculated as:
Subtract 22 from both sides
<u>Question 5</u>
If LP and LQ are linear pairs, then:
So:
Substitute
Subtract 90 from both sides
<u>Question 6</u>
--- S and T are supplementary
--- T and U are complementary
Subtract both equations
Make U the subject
This means that:
Hence, is an obtuse angle
<u>Question 7</u>
Obtuse angles are greater than 90 degrees but less than 180.
This means that their supplement must be an acute angle (i.e. less than 90)
<u>Question 8</u>

Answer:
Step-by-step explanation:
Solve absolute value.
There are two possibilities.
First possibility:
No solution.
Second possibility:
Answer:
Step-by-step explanation:
A plane took 1.5 hours to complete the journey of 915 miles.
Therefore, constant of proportionality will be,
k =
y = 610x
Time in hours (x) Distance in miles (y) Constant
1 y = 610x ⇒ y = 610 miles 610
1.5 915 610
2 y = 2 × 610 = 1220 miles 610
2.5 y = 2.5 × 610 = 1525 miles 610
