Sum of interior angles in a pentagon=540°
148+112+2x+2x+10+90=540
360+4x=540
4x=540-360
4x=180
x=180/4
x=45°
So basically you use the ratio they have given you. You either multiply by 2 if image is enlarged or divide by 2 if it is reduced. (Keep in mind I got the 2 from your ratio : 1inch : 2inches) Therefore the find the original width, you multiply 10 by 2, giving you 20 inches.
Like 9 and 9? 9 is a multiple of 3 and 9 time 9 is 81
Answer:
it will be equal to
okay....
Step-by-step explanation:
volume of a cuboid = l × b × h
( where l = length, b = width , h = height )
so volume of given cuboid = ( 3x × 2x × 2x )
hence volume =
