The equation of a circle with center (a , b) and radius r is :
===================
Now ,let’s apply what we have learnt:
The equation of the circle with center (a , b) = (2 , 6) and radius r = 2√3 is :
9514 1404 393
Answer:
∠3 = ∠5 = ∠7 = 65°
∠2 = ∠4 = ∠6 = ∠8 = 115°
Step-by-step explanation:
In this geometry, all of the acute angles are congruent, and all of the obtuse angles are congruent. The acute and obtuse angles are supplementary.
Here, the acute angles all have odd numbers; the obtuse angles all have even numbers.
Odd-numbered angles measure 65°.
Even-numbered angles measure 180° -65° = 115°.
