The measure of ∠SQR is 75°.
Explanation
Since the problem states that ∠PORT measures 75°, and asks for the measure of ∠SQR, it suggests that these angles are related in some way—likely they are either equal or supplementary based on the geometric configuration. Without a diagram, the most common scenario is that ∠PORT and ∠SQR are either vertically opposite angles, corresponding angles, or part of the same geometric figure where angles are equal.
Given typical geometric conventions, if ∠PORT and ∠SQR are corresponding or vertically opposite angles in a figure, then:
Steps:
- Recognize the relationship: If the angles are corresponding or vertically opposite, then they are equal.
- Therefore, $\boxed{\text{∠SQR} = 75°}$.
Therefore, the measure of ∠SQR is 75°.
