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°
7 plus 7 equals 14. Add one to that and you have 15 which is the answer.
