Because ∠2 is a diameter away from arc ST, ST is two times larger than ∠2. So, the answer is:

m∠2 = 1/2(mST)

Inscribed angles (angles on the line of the circle) are one half of its opposite arcs.
Therefore m <2 = 1/2 (mST), the 2nd one down (or middle) answer.
For example, if ST were 80°, then m <2 would be 40°.

Can someone explain how to do this and add the formula please
lisabon 2012 [21]

Answer:

5 is 35 and 6 is 50

Step-by-step explanation:

To solve 5, you need to know how many degrees is the line, which is 180 because lines are 180 degrees. You then subtract 110 from 180 which equals to 70. What you have left now is 2k. A number times 2 will equal to 70, so k=35.

For 6, if you ever see two lines intersecting each other, it means that it is 360 degrees. We already have one angle, which is 120. The other angle is d+70 degrees, and any angle that is reflecting the other angle will have the same value. So, d equals 50
