Answer:
Step-by-step explanation:
If we drew an auxiliary line parallel to line 
and line 
that intersects the vertex of 
, we would form three angles, one of them being
The largest of these angles corresponds with the angle marked as 
.
The angle on the bottom right corresponds with the angle next to the one marked as 
. Therefore, its measure is 
.
Since there are 
in a circle, we can now write the following equation:
.
Answer:
25 wooden boards
Step-by-step explanation:
Given that:
Width of wooden board = 6 inches
Number of boards required to build a fence of 150 inches long if there are no gaps :
The lenght of fence / width of wooden board
= 150 inches / 6 inches
= 25 wooden boards
2160 - 180 - 432 = 612
Each parallelogram is 3 square inches
divide by 3
612/3 = 264 parallelograms to complete the quilt.
Steps to my answer:
