Answer:

Explanation:
The equation is:

To get rid of the denominator, multiply both sides by 3. Then you have:

To get x alone on one side, add 2 to both sides. Then you have:

Sonnet 18 is SUCH a good one!!!! i love that one. :D a sonnet actually has a bunch of couplets!
an example is:
shall i compare thee to a summer's day?
Rough winds do shake the darling buds of May,....
Hope this helps!!
Answer:
here,
<y +<z = 150 ° ( sum of two sides of interior angle is equal to exterior angle)
or,65°+<x=150°
or, <x=150°-65°
or, <X = 85°
Now,
<x +<y+<z=180° [ the sum of three angles of a triangle is 180°]
or, < x+65°+85°=180°
or, <x =180°-150°
or,< x=30°
Then,
<x+<y=<z
30° +65° =95 °
or, 180° -95° = 85 °
To get <XZW,
180° - 85 ° = 95°[ The exterior angle is equal to the differnce of 2 interior angles through 180 °]
