Answer:
<u>Question 11:</u>






<u>Question 12:</u>
,
,
and 
<u>Question 13: </u>
AC and BD are perpendicular lines, and they are diagonals
Step-by-step explanation:
<u>Question 11</u>
Given


See attachment for Rhombus
Required
Determine the indicated sides
Solving (a): 
Diagonal CA divides
into 2 equal angles
i.e

So:

Solving (b): 
The angles at E is 90 degrees because diagonals AC and BD meet at a perpendicular.
So:

Solving (c): 
First, we calculate
, considering
:





To calculate
, we have:



Solving (d): 
From the rhombus

Where

So:


Solving (e): 
To do this we consider 
Using the tan formula

and 
So:



Solving (f): 
This is calculated as:

Where



<u>Question 12: Isosceles Triangle</u>
In the rhombus, all 4 sides are equal;
So, the isosceles triangle are:
,
,
and 
<u>Question 13: </u>
AC and BD are perpendicular lines, and they are diagonals
