Answer:
m<ABC=51°
Step-by-step explanation:
The inscribed angle is half the measure of the intercepted arc. This means that angle ABC=1/2 arc AC
Using this, let's make an equation
5x+11=(1/2)(16x-26)
5x+11=8x-13
11=3x-13
24=3x
x=8
Now go back to angle ABC and substitute for x
5(8)+11=51
m<ABC = 51
m<ABC = 1/2 arc AC
(5x + 11) = 1/2(16x-26)
Plug it in
5(8) + 11 = 51
