Complete the statement with the corresponding congruent part. If △TRS ≅ △DEF, then stack S T with bar on top ≅ ? Group of answer choices top enclose T R end enclose top enclose F D end enclose top enclose E F end enclose stack D F with bar on top angle F D

|ST| = |FD|

Step-by-step explanation:

Two triangles are aid to be congruent if all their three sides are equal to each other and their three angles are equal to each other. The congruent sides must not be in the same position especially when one triangle is the reflection of the other triangle.

Given that ΔTRS is congruent to ΔDEF. Also they have the same congruent part, hence:

|TR| = |DE|, |TS| = |DF|, |ST| = |FD|

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
