Answer:

x = 70

Step-by-step explanation:

The angle between the tangents is the supplement of the intercepted arc:

x° = 180° -110°

x° = 70°

<em>Alternate solution</em>

The exterior angle x° is half the difference of the intercepted arcs. Long arc ACB is 360° -110° = 250°, so we have ...

x° = (250° -110°)/2 = 140°/2

x° = 70°

If you work this alternate solution generically, you find it is the same as the first solution.

x = ((360 -AB) -AB)/2 = (360 -2AB)/2 = 180 -AB

Select the correct answer

NemiM [27]

let f(r)=sin^3r/cos^3r

so f(-r)= (sin(-r)/cos(-r))^3

=(-sinr/cosr)^3

=-f(r)

so it is odd function
