Answer:
2 x (3 y^3 + 2)
Step-by-step explanation:
Simplify the following:
2 x + x + x + 2×3 y y x y
2 y×3 y = 2 y^2×3:
2 x + x + x + 2×3 y^2 x y
2×3 = 6:
2 x + x + x + 6 y^2 x y
6 y^2 x y = 6 y^(2 + 1) x:
2 x + x + x + 6 y^(2 + 1) x
2 + 1 = 3:
2 x + x + x + 6 y^3 x
Grouping like terms, 2 x + x + x + 6 y^3 x = 6 x y^3 + (2 x + x + x):
6 x y^3 + (2 x + x + x)
2 x + x + x = 4 x:
6 x y^3 + 4 x
Factor 2 x out of 6 x y^3 + 4 x:
Answer: 2 x (3 y^3 + 2)
Those two angles are congruent.
_____
The angles are corresponding parts of congruent triangles (CPCT). Triangles OBA and OCA are right triangles congruent by the HL postulate. The "H" is segment OA. The "L" is the radius, OB or OC. Of course the angles at B and C are 90° as with any radius and tangent line.
The answer is C. Hope this helps
