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:
It is not ''significant''
Step-by-step explanation:
Let's call the event
A : ''Answer a question correctly if a random guess is made''
Now we calculate the probability for the event A
In the exercise A occurs in only one way and the total cases are the number of possible answers
An event B is ''significant'' if
⇒A it is not a ''significant'' event
Answer:
1. a. Corresponding angles
b. alternate exterior angles
c. same side interior angles
2. answer is 9
Step-by-step explanation:
4x+2=7x-25
subtract for on both sides
2=3x-25
Add 25 on both sides
27=3x
Then divide 3 on both sides
x=9
There is no question though ?
