HELP IN NEED!
laiz [17]

Answer:

AB=12\sqrt{3}\ cm

Step-by-step explanation:

If AB is tangent to the circle, then angle ABO is right angle and triangle AOB is special 30^{\circ}-60^{\circ}-90^{\circ} triangle. In this triangle, the leg that is opposite to the angle of 30° is half of the hypotenuse. Thus,

AO=2BO=2\cdot 12=24\ cm.

By the Pythagorean theorem,

AB^2=AO^2-BO^2,\\ \\AB^2=24^2-12^2,\\ \\AB^2=576-144=432,\\ \\AB=12\sqrt{3}\ cm.

Given that cos theta = -12/13 and theta is in the second quadrant, find this function. sin theta=​
elena-14-01-66 [18.8K]
5/13

The x value is negative (second quadrant). 13 is the hypotenuse. So the missing side is 13^2 = (-12)^2 + y^2.

Sin theta is the opposite (5) over hypotenuse (13).
