Answer 2

Given Information:

We are given the following information: - aOb - OA = AA = AА = АА = АВ - A, B - A, В - A, В, ОВ = B, B = 18 cm (see Figure 6)

Solution:

To find ОВ, ОВ, ОВ, we need to analyze the given information and apply the relevant geometric concepts.

From the given information, we can see that OA = AA = AА = АА = АВ. This implies that the triangle OAA is an isosceles triangle, where OA and AA are equal sides.

Since OA = AA, we can conclude that angle OAA is also equal to angle AAO. This means that triangle OAA is an equilateral triangle, where all three angles are equal to 60 degrees.

Now, let's consider triangle OAB. We know that OA = AA = AА = АА = АВ, so OA = AB. Since triangle OAA is an equilateral triangle, angle OAB is equal to 60 degrees.

Using the fact that the sum of the angles in a triangle is 180 degrees, we can find angle AOB: angle AOB = 180 - angle OAB - angle OBA angle A
