10, 20w, 2w, and we are factors of 20w and 40wz
Answer:
√245 or 15.65247...
Step-by-step explanation:
a² + b² = c²
14² + 7² = c²
196 + 49 = c²
245 = c²
√245 ≈ c
Step-by-step explanation:
WX is parallel to YZ and WZ is also parallel to XY
21 line segments are needed to connect each dot to each other dot.
Since, there are 7 dots on a piece of paper such that no 3 dots are in a straight line.
We know that a line segment has two endpoints.
Number of line segments formed by <em>n</em> points = 
So the required number of line segments are needed to connect given 7 dots (each dot to each other dot
)


Hence, 21 line segments are needed to connect each dot to each other dot.
