Answer:
A=45 square inches
Step-by-step explanation:
First find the height using Trig
Tan(45)=x/6
x=6tan(45)
x=6
Then area of a parallellogram is base x height so
A=7.5 x 6
A=45 square inches
This is pretty simple once you figure out the trick.
All you have to do is make the args common.
Meaning 
is nothing but 
Which is nothing but: 
.
Now using the scorpion tail method, this equation can be reframed to being: 
. You bring 6 to the other side and it'll become: 
Factorise it and you get: 
Henceforth, the solution would be 
and 
. :D
