Answer 1

Recall that dilations preserve angle measures, therefore:

`m\angle S^(\prime)T^(\prime)U^(\prime)=m\angle STU.`

We are given that:

`m\angle STU=140^(\circ).`

Therefore:

`m\angle S^(\prime)T^(\prime)U^(\prime)=140^(\circ).`

Answer:

`m\angle S^(\prime)T^(\prime)U^(\prime)^{}=140^(\circ).`
