Step-by-step explanation:
Here is the answer to your question as This is the way I think it is solved
Answer:

Step-by-step explanation:
Given the equation:

To find:
The solutions of given equation in the range [0, 2
) i.e. 0 can be in the answer but
can not be there in the answer.
Solution:
Taking
common, we get:

The solutions can be given as:
OR 
Let us solve both the equations one by one:
First equation:

Second equation:

Therefore, the answers as a comma separated list are:

Let us assume then that the center is the origin. If the major axis is 18, then a = 9 and a^2=81. If the minor axis is 16, then b = 8 and b^2=64. Now you can write the equation. Remember that this ellipse is vertical and so a^2 goes under y^2
∠A, ∠B, ∠C - interior angles of a triangle.
∠A 1 , ∠B 1 , ∠C 1 - exterior angles of a triangle.
∠A + ∠B + ∠C = 180°
∠A + ∠A 1 = 180°
Therefore: ∠A 1 = ∠B + ∠C ( two remote interior angles )
Answer:
An exterior angle of a triangle is equal to the sum of the two remote interior angles.
