If triangle dgh is congruent to triangle def find the value of x
Rom4ik [11]

Answer:

x = 25

Step-by-step explanation:

\triangle DGH\sim\triangle DEF... (given)

\frac{DG}{DE} =\frac{GH}{EF}

\frac{52}{91} =\frac{x+3}{2x-1}

\frac{4}{7} =\frac{x+3}{2x-1}

4(2x - 1) = 7(x + 3)

8x - 4 = 7x + 21

8x - 7x = 21 + 4

x = 25
