LETS prove the 2nd part of the Question
Here concept of right angles is used
We can see BA is perp to BD
and BC is perp to BE
We have to prove angle 1 = angle 3
i will denote angle by a
therefore we need to prove a1 = a3
as BA is perp to BD hence angle between them will be 90 degree
a1 + a2 = 90 degree
Similarly BC is perp to BE
a2 + a3 = 90 degree
as both equations add up gives 90 degree so will equate them
a1 + a2 = a2 + a3
which means a1 = a3
Hence Proved

Answer:
256
Step-by-step explanation:
Hope this helps!
If not, I am sorry.
since all sides are equal, which means all angles must also be equal to one another
all angles =60°
solving 7x-3=60
7x=63
x=9
similarly 11 y+5=60
11y=55
y=5

The inequality
From the question, we understand that;
the number of p used is more than the number of s
<em>more than means greater than.</em>
So, the inequality is:

To represent this on a number line.
First, we identify the position of s (i.e. scarf)
implies that p is any point to the right of s
