Answer: Hey, you need to add a photo, once you do so I will edit my answer
X is equal to 100 and Y is equal to 16
The number in the set that is a natural number is 402
We know that these two angles are equal to each other (There is the "congruent" sign) so we can set them equal to each other and solve for x
3x - 17 = 25 - 3x
(3x + 3x) - 17 = 25 + (-3x + 3x)
6x + (- 17 + 17) = 25 + 17
6x/6 = 42/6
x = 7
Hope this helped!
