Question

a triangle has angle measurements of 38°, 137°, and 5°. what kind of triangle is it?
acute right obtuse

Explanation:

Step1: Recall triangle types

• Acute triangle: all angles < \(90^\circ\).
• Right triangle: one angle = \(90^\circ\).
• Obtuse triangle: one angle > \(90^\circ\).

Step2: Analyze given angles

The angles are \(38^\circ\), \(137^\circ\), \(5^\circ\). Here, \(137^\circ>90^\circ\).

Answer:

obtuse (since one angle, \(137^\circ\), is greater than \(90^\circ\), so the triangle is obtuse)
