Answer:
sum of exterior angles of polygon = 360°
therefore,
z = 360 - (105+145)
z = 360 - 250
z = 110°
You can solve with the formula for cuadratic equations:
x=−b±√b2−4ac
2a
To solve for the answer of the question above, let x be the number of words on the list. As stated above, 2/3 of this is the number of words Martina needs to memorize which is 12. This may be expressed as,
(2/3)(x) = 12
Solving for x in the equation gives an answer of 18. Therefore, there are 18 words on the list.
