Answer:
93°
Step-by-step explanation:
It's given that angle AOC is 87°. BC is a straight line so, angle E=180°-87°=93°
Since they are similar you need to start by making ratios for each pentagon.
1.8/2.4 is the first and x/3.6 is the second. Now set them equal to each other and cross multiply.
1.8 X
___ = ____
2.4 3.6
2.4x= 6.48 Now divide both sides by 2.4
2.4x= 6.48
___ ____
2.4 2.4
X= 2.7
I have no idea what that is so sorry
Answer:

Step-by-step explanation:
We need to write a quadratic equation so we can use standard quadratic equation:

Plug the given points to get three equations.
for (7,4), we plug x=7 and y=4

...(i)
similarly using other two points, we get:
...(ii)
...(iii)
Now we solve those three equations by any method like substitution, or matrices or by any method and get:

Now plug these values into
, we get final equation as:
