What percent is represented by the shaded area?

30%

Step-by-step explanation:

So originally it is 6/20 to get a percentage the denominator needs to be 100 so you multiply both the numerator and denominator by 5 which gets you 30/100 and 30/100 equals 30%

Hope this helps!

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint
