Answer:
D) ∠T, ∠R, ∠S, RS, ST, RT
Explanation:
Given ∆RST with RS=23.7 cm, ST=35 cm, TR=48 cm, you want the angles and sides listed in increasing order.
Side lengths
In increasing order, the side lengths are ...
23.7 < 35 < 48
The corresponding names of these sides are RS, ST, RT.
The last answer choice lists the sides in this order.
Angles
Angles, least to greatest, are opposite the least-to-greatest sides. The angle vertex is the triangle vertex not listed in the side name:
shortest side RS is opposite smallest angle T
longest side RT is opposite largest angle S
Hence, the angles in order are ∠T, ∠R, ∠S. (matches the last choice)
