  6. 135°

  7. 135°

Step-by-step explanation:

You have to assume that the figure is a regular octagon, so has central angles equal to exterior angles equal to 45°.

6. A regular anything is circumscribed by a circle, so the measure of any inscribed angle is half the measure of the corresponding central angle. That is, ∠BET =∠TBA = (45°)/2, so their sum is 45°. ∠BOT is the supplement of that, 180° - 45° = 135°.

__

7. ∠GIT + ∠ITS is the same measure as one internal angle of the octagon. That is the supplement of the exterior angle we identified above as being 45°.

  ∠GIT + ∠ITS = 135°

Step-by-step explanation:

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
