since the equation for both triangles have A^2 + B^2 you can think of the two equations for C^2 and n^2 as a system of equations such as to what a equals in the first equation for A^2 + B^2 in the second question after you substitute to what equation do you get ​

Given:

a² + b² = c²

a² + b² = n²

To find:

Substituting both equation to get a new equation

Steps:

We know,

a² + b² = c²

a² + b² = n²

Now if we substitute a² + b² to equal to c², in equation a² + b² = n² we get,

a² + b² = n²

       c² = n²

         c = n

Therefore we get the new equation as c = n

Happy to help :)

If you need any help, pls feel free to ask

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
