Given: ∠a ≅∠d, ∠b ≅∠e m∠c = x, m∠f = 2x−30° find: m∠c this is 2 seperate triangles abc is one triangle and def is a different triangle

Since <A = <D and <B = <E, it must be true that the third angles <C = <F  (the triangles are similar).

If <C = x and <F = 2x-30  then you need to find x for which <C = <F is true:

x = 2x-30

and that holds for x=30

So m<C=30 degrees

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
