Respuesta :
a^2 + y^2 = c^2...where c is ur hypotenuse and a and b are ur legs
35^2 + y^2 = 37^2
y^2 = 37^2 - 35^2
y^2 = 1369 - 1225
y^2 = 144...take sqrt of both sides, eliminating the ^2
y = sqrt 144
y = 12 <===
a^2 + b^2 = c^2
15^2 + b^2 = 25^2
b^2 = 25^2 - 15^2
b^2 = 625 - 225
b^2 = 400
b = sqrt 400
b = 20 <===
35^2 + y^2 = 37^2
y^2 = 37^2 - 35^2
y^2 = 1369 - 1225
