Question

Find the measure of arc BC?

Answer 1

Answer:

129

Step-by-step explanation:

Since,

AD = BC

AD = 3x + 24

BC = 4x - 11

3x + 24 = 4x - 11

4x - 11 = 3x + 24

4x - 3x = 24 + 11

x = 35

BC = 4x - 11

= 4 ( 35 ) - 11

= 140 - 11

BC = 129

Answer 2

Answer:

$AB=BC$

$3x+24=4x-11$

$3x-4x=-11-24$

$x=35$

$BC=4\times 35-1$

$=140-11$

$=129$
