A photograph measures 10 inches wide by 18 in. Long the picture is reduced so that the length is 6in What is the new width show calculations

divide 10 by three, you should get 3.33

Step-by-step explanation:

it has an area of 19.98  and a perimeter of 18.66

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
