Its an isosceles triangle and just for future reference, you can google the types of triangles and you will find websites with definition and answers
X + Y = 180 so X = 122. W = X = 122. Z = Y = 58
I suppose you want to know such number. Since we have a two digit number consisting of two consecutive integers, the only possible numbers are:

Since we sorted all the cases out, we simply have to check which one satisfies the requirement. For each number, we'll write four times the the sum of its digits, and add 6, hoping to get the original number.



So, the answer is 34.
I believe that the answer to this question is 30.345 cm
