as given in the diagram this is equalatral triangle where all the side and angle are same
the sum of the three angle in a triangle is always 180 degrees
as in this triangle all of the angles are the same its

35r+10+20p
you would multiply by 5 to all the numbers in the parantheses
The correct answer is D X=-3, since the directrix is always the opposite distance from the vertex as the focus is.
The required distance walked by Jane diagonally is 105.7 meters.
Given that,
A football pitch is 97 m long and 42 m wide. Bill walks from one corner to another around the outside. Jane walks diagonally across the pitch. How much further Bill walk is to be determined.
<h3>What is simplification?</h3>
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Length = 97
Width = 42
Diagonal = 
Diagonal = 105.7 meters.
Thus, the required distance walked by Jane diagonally is 105.7 meters.
