Find the percent of the following problems: 2.) What percent of 90 is 72?

5%

Step-by-step explanation:

Let p be the unknown percent.

Put this into a basic equation - (p/100)*90=72

Simplify this expression and you will get 5%

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

how many players are there?
