Step-by-step explanation:
If the ratios of the 3 pairs of corresponding sides of the 2 triangles are equal , then the triangles are similar (SSS postulate )
the3 ratios of the 2 triangles , left to right are all equal to
Then the triangles are similar by the SSS postulate
the corresponding angles of similar triangles are congruent, then
∠ c = 60°
Also both triangles have 3 congruent sides and are therefore equilateral triangles with all angles equal to 60°, so
c = 60°
