<h2>
It is an obtuse angle.</h2>
Step-by-step explanation:
Obtuse: An obtuse angle is an angle more than
but less than
.
Example :
,
etc.
Acute : An acute angle is an angle less than 
Example :
,
etc.
Straight : A straight angle is
.
Right: A right angle is
.
Since the angle is more than
but less than
. So, it is an obtuse angle.
Use the formula,
I = Prt
P = Principal amount = 400
I = interest = 18
r = annual rate
t = time in years = 9/12 = 3/4
so,
18 = 400*r*3/4
r = 0.06
so the annual interest rate is 0.06 or 6%.
Subtract 6x from 9x
-15=3x-6
add 6 to both sides
-9=3x
divide 3 from both sides and -3=x
