Let the money spent by John = y
and Amy=x
ATQ
x+y = $29
It is given that jon spend 5 more than Amy. SO he spend
x +5
x+y = $29
x+x+5=$29
2x = 29-5
2x= 24
x = 24/2 =12
So Amy spend $ 12 and Jon spend x+5 = 12+5 = $17
Solution:
we are given that
Inscribed angle
Intercepted arc
As we know that the Inscribed angle is Half of the measure of the intercepted arc.
So we can write

It's a reflection over the y axis because 'a' represents 'x' and if 'a' is negative it flips to the other side leave 'b/y' to remain the same
