Solution: Mika will be 36 meters away from the current location.
Explanation:
It is given that Gretchen and Mika are at the same point when Gretchen runs backward at the speed of 4 m/s in opposite direction to pick her baton and Mika runs in the direction of the race at the speed of 3 m/s.
We have find the distance covered by Mika form the current location in the time when Gretchen picks her baton up.
Let the time taken by Gretchen picks her baton up be t.
It is given that 48 meters from her current location she dropped her baton. Since she is running at the speed of 4 m/s.
Gretchen will pick up the baton in 12 seconds.
The distance covered by Mika in 12 seconds is
Therefore, Mika will be 36 meters away from the current location.

Answer:
the perimeter is 40 ft
Step-by-step explanation:
to find the perimeter you add up all the sides
The triangles ΔLMN and ΔPQR are similar as per the AA similarity postulate. This is because ΔLMN and ΔPQR have two pairs of congruent corresponding angles: ∠LMN and ∠PQR, and ∠LM and ∠PQ, contemporaneously proving the AA (Angle-Angle) similarity postulate.
The given problem involves two triangles ΔLMN and ΔPQR. Here, ΔLMN is the original triangle, and ΔPQR is a dilated version of ΔLMN by a scale factor of one-half centered at point M.
For the AA (Angle-Angle) similarity postulate, we need to confirm that two angles of one triangle are congruent to two angles of another triangle. If we can establish this, we can deduce that the two triangles are similar.
Firstly, it is given that m∠LMN is 90°. As a property of dilation, it preserves the measures of angles. This means that m∠PQR will also be 90°. Secondly, since the dilation happens at point M, ∠M of ΔLMN will be the same as ∠P of ΔPQR. Thus, we have two sets of corresponding angles (LMN and PQR, and LM and PQ) that are congruent, satisfying the AA similarity postulate. Therefore, we can conclude that ΔLMN is similar to ΔPQR by the AA similarity postulate.

The triangles ΔLMN and ΔPQR can be proven similar by the AA similarity postulate.
The triangles ΔLMN and ΔPQR are similar to each other by the AA (Angle-Angle) similarity postulate.
AA similarity postulate states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
In this case, since ΔPQR is a dilation of ΔLMN with a scale factor of one half, the angles of ΔPQR are congruent to the corresponding angles of ΔLMN.
Therefore, we can conclude that ΔLMN ~ ΔPQR by the AA similarity postulate.
