Multiply 75 by 0.20.
7.5x5000=
The third angle is 30°, and there's no way to determine the lengths of the sides from the information given.
75% of 90 = 75% * 90 = 0.75 * 90 = 67.5
Count them.
It has 75 sides.
A pentagon is a 5-sided figure, and the perimeter is the sum of the lengths of all the sides. A pentagon with 15-inch sides, will have 5 x 15 inches = 75 inches as its perimeter.
Multiply 75 by 0.20.
there may be a specific name for it and if thats what your looking for IDK but my geometry teacher always told us if you didnt know that you can always add the word -gon after the number to make the figure you will need. 75-gon
5X = 75 divide both sides integers by 5 (5/5)X = 75/5 X = 15 ----------------check 5(15) = 75 75 = 75 checks

The third angle is 30°, and there's no way to determine the lengths of the sides from the information given.
74 sides
You recognise that 20% is one-fifth so you multiply 75 by 5...
75% of 90 = 75% * 90 = 0.75 * 90 = 67.5
