Answer:
m∠BPD = 120
mBC + mAD = 120°
Step-by-step explanation:
according to intersecting chord theorem: The measure of the angle formed by two chords that intersect inside the circle is the sum of the chords' intercepted arcs.
m∠BPD = (M∠BD + M∠CA)
= (70 + 170)
= (240)
m∠BPD = 120
We know that a circle has a total of 360° around the center of circle. To find the measure of the remaining measure of angle of arcs, subtract them from the whole that is 360°
mBC + mAD = 360 - ( 70 + 170 )
= 360 - 240
mBC + mAD = 120°

Answer:
- 1
Step-by-step explanation:
Let the slope of one line be 's' , then according to the given condition that the slope of second line is negative reciprocal of the first , We obtain the slope of the second line as .
So, the product of both the slopes is given by
This shows that whatever the slopes may be if they are negative reciprocal of each other then their product will always be -1
Answer:
6 books
Step-by-step explanation:
Since she spent $32 on 4 books then the cost of one = 32/4 = $8
She spent $16 on books and one book costs $8, then the number of books she bought = 16/8 = 2 books
Altogether, she bought 4 + 2 = 6 books
