First you need to c<span>onvert the given percentage into fraction by dividing it by 100 and removing percentage symbol (%).
Then you reduce the fraction into simplest forms.
Finally you write the </span> fraction turned simplest form to a ratio by writing
the numerator first,then the denominator.
Example:50%=
.
=1:2
180 = 65 + (x-5) + x
-65 -65
115 = x - 5 + x
115 = 2x - 5
2x = 120
x = 60
The angle measures are 65, 60, and 55 degrees.
V= LWH so 3.75cm^3 or 3 (3/4)
Multiply those three sides and it comes out to 3.75
