How To Find The Value Of X And Y In Similar Triangles. Triangle def is shown with side de labeled 6, ef labeled 4, and fd labeled x. Similar triangles find the value of x 1 see answer advertisement advertisement annettawalker17 is waiting for your help.

X notice in the right triangle, x is the opposite side of the given angle and the given value of 15 meters is the adjacent side of the given angle. The legs of the triangle are congruent, so x =7. Take the ratio of the shortest sides of both the triangles and the ratio of the longest sides of both the triangles.

Similar Triangles Have The Same Proportions.

Now that we are done with the congruent triangles, we can move on to another concept called similar triangles. How to find the missing side length given two similar triangles. For the pair of similar triangles, find the value of x.

The Following Triangles Are Similar.

{ z 2 = 25 + x 2 y 2 = 16 + x 2 81 = z 2 + y 2. Since triangles abc and def are similar, their corresponding sides are in the same ratio. There are three right triangles in your picture given by the three right angles (notice that ∠ a b d is right).
