Question

a triangle has one angle that measures 17 degrees, one angle that measures 103 degrees, and one angle that measures 60 degrees. what kind of triangle is it? a. equilateral triangle b. acute triangle c. obtuse triangle d. right triangle

Explanation:

Step1: Recall triangle - type definitions

An equilateral triangle has all angles equal to 60°. An acute triangle has all angles less than 90°. An obtuse triangle has one angle greater than 90°. A right - triangle has one angle equal to 90°.

Step2: Analyze the given angles

The given angles are 17°, 103°, and 60°. Since 103° > 90°, the triangle has one obtuse angle.

Answer:

C. obtuse triangle
