Given:
Triangles ABC and DEF are similar triangles.
AB = 6 m, BC = 16 m, CA = 15 m, DE = x, EF = 32 m, FD = y
To find:
The values of unknown sides, i.e., x and y.
Solution:
We know that the corresponding parts of similar triangles are proportional and triangles ABC and DEF are similar triangles, so
Now,
Similarly,
Therefore, the measure of unknown sides are x = 12 m and y = 30 m.
The answer is A. 40+45 and here is the steps
