The sum of 2 positive numbers is 29. if one of them is 5 more that that of other, find the numbers.

12 and 17

Step-by-step explanation:

smaller number = (29-5)/2 = 24/2 = 12

greater number = 12 + 5 = 17

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
