Answer:

PD = 18

EQ = 4

Step-by-step explanation:

Given:

AP = 3,

PQ = 5,

QB = 7,

CP = 2,

QD = 14

Required:

1. PD

2. EQ

SOLUTION:

1. Based on Intersecting Chords Theorem,

AP*PB = CP*PD

AP = 3

PB = PQ + QB = 5 + 7 = 12

CP = 2

PD = ?

Plug in the values into the equation

3*12 = 2*PD

36 = 2*PD

Divide both sides by 2

\frac{36}{2} = PD

18 = PD

PD = 18

b. Based on Intersecting Chords Theorem,

EQ*QD = AQ*QB

EQ = ?

QD = 14

AQ = AP + PQ = 3 + 5 = 8

QB = 7

Plug in the values into the equation

EQ*14 = 8*7

EQ*14 = 56

Divide both sides by 14

EQ = \frac{56}{14}

EQ = 4
