Answer:
x = 146°
Step-by-step explanation:
parallelogram property
x + 34 = 180
x = 146
A polygon is any figure sided with three sides and above such that triangle (3) is the smallest polygon. A nonagon is a polygon with 9 sides. To get the sum of interior angles of a polygon we use the formula;
(n-2) 180 or (n-4)90 where n is the number of sides.
Therefore, for a nonagon the sum of interior angles = (9-2) 180 = 1260 degrees
If we add all the angles we should get 1260, considering the remaining angles to be each x
Thus 138+154 +145 +132 +128 +147 +130 + x +x =1260
= 974 + 2x = 1260
= 2x = 286
= 143
therefore, each of the other angles was 143
Answer:
Her work includes putting labels on 750 books. How many minutes will she need to finish labeling all books if If she takes no breaks and
Step-by-step explanation:
If you have six sopranos and eight baritones, you have fourteen musicians in total.
The number of possible quartets that you can get with 14 musician is:



Now, the number of possible quartets without a soprano that you can have is:



Therefore, the number of quarters that contains at list one soprano will be the number of possible quarters minus the number of quarters without a soprano:

We can conclude that the director can choose a quarter which contains at least one soprano in 931 ways.
Answer:
The width w of the rectangular park = 1/2
Step-by-step explanation:
Given
The length of the rectangular park l = 2/3 miles
The area of the park A = 3/9 square miles
To determine
The width of the rectangular park w = ?
Using the formula of the Area of the rectangle


∵ Fraction rule: 


Therefore, the width w of the rectangular park = 1/2
