Answer:

∠ XYZ ≈ 66.4°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cosY = \frac{adjacent}{hypotenuse} = \frac{XY}{YZ} = \frac{6}{15} , then

∠ Y = cos^{-1} (\frac{6}{15} ) ≈ 66.4° ( to 1 dec. place )

Answer:

= ( {x}^{a}  -  {3y}^{2b} ) \times ( {x}^{2a}  +  {3x}^{a}  {y}^{2b}  +  {9y}^{4b} )

Step-by-step explanation:

{x}^{3a}  - 27 {y}^{6b}

( {x}^{a}  {)}^{3}  -  {3}^{3}  \times ( {y}^{2b}  {)}^{3}

( {x}^{a}  {)}^{3}  - (3 {y}^{2b}  {)}^{3}

( {x}^{a}  -  {3y}^{2b} ) \times (( {x}^{a}  {)}^{2}  +  {x}^{a}  \times  {3y}^{2b}  + ( {3y}^{2b}  {)}^{2} )

\boxed{\green{= ( {x}^{a}  -  {3y}^{2b} ) \times ( {x}^{2a}  +  {3x}^{a}  {y}^{2b}  +  {9y}^{4b})}}
