Answer:
a) m∠BPD = 120°
b) m∠BC + m∠AD = 120°
Step-by-step explanation:
a) To solve for question a, we make use of a theorem called the intersecting chord theorem. This states that:
The measure of the angle formed by two chords that intersect inside a circle is the average of the measures of the intercepted arcs.
The Interior angle =( The larger exterior arc + The smaller exterior arcs) ÷ 2
The larger exterior arc (m∠BD) = 170°
The small exterior arc (m∠CA) = 70°
m∠BPD = m∠BD + m∠CA/2
m∠BPD = 170° + 70°/2
= 240°/2
= 120°
b) We are to find m∠BC + m∠AD
The sum of exterior angles in a circle = 360°
360° = m∠BD + m∠CA + m∠BC + m∠AD
360° = 170° + 70° + m∠BC + m∠AD
360° = 240 + m∠BC + m∠AD
360 - 240° = m∠BC + m∠AD
Thererefore,
m∠BC + m∠AD = 120°
Answer:
C 117
Step-by-step explanation:
<2 = 63 vertical angles
<2 = <4 alternate interior angles
<4 + <7 = 180 straight line
63 +<7 = 180
subtract 64 from each side
<7 = 180-63
<7 = 117
Answer:
given (0,0) and (12,y1)
the distance formula states taht
the distance between the points (x1,y1) and (x2,y2) is
D=
given
D=13
x1=0, y1=0
x2=12
square both sides
minus 144 both sides
sqrt both sides
+/-5=y2
the points are
(12,5) and (12,-5)
