Answer:

y=5 and x=12 you have to use a^2+b^2=c^2 to find y so you would do 3^2+4^2=25 however u have to square root of 25 is 5 and then use c^2-b^2=a^2 to find x. HOPE IT HELPS. GOOD LUCK

Answer:

y = 5

Step-by-step explanation:

In a right angled triangle the square of the long side is equal to the sum of the squares of the other two sides.

a² + b² = y²

3² + 4² = y²

9 + 16 = y²

y² = 25

y = 5
