It is that the angle has to be formed by two pairs of congruent/corresponding sides of the triangle
D=dimes
q=quarters
if she has 12 coins then
12-d=q she has 12-d quarters
we dont know how much money she has unless we know d.
she could have 12 dimes and 0 quarters or 11 dimes and 1 quarter etc. we need more information to solve.
We cant answer this because we dont know what the 2 triangles look like
