In the diagram of circle 0, two tangents have been drawn from exterior point P to the circle at points A and B. (a) If mAB =105 , then determine the measure of

 75° is the measure of the angle formed by the tangents originating at point P.

I am guessing at the rest of the question, but its usually what this leads to.

Step-by-step explanation:

The measure of that exterior angle is half of the difference between the major arc and the minor arc inscribed by the tangents.

The minor arc given is 105. Subtract that from 360 to get the measure of the major arc.  360 - 105 = 255.

The difference between the major arc and the minor arc is 255 - 105 = 150

Half of that is 150÷2 = 75.

So the measure of the exterior angle APB is 75°

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
