Question

Determine the number of acute, right, and obtuse angles.

• A. 2 acute angles, 0 right angles, and 1 obtuse angle
  
• B. 1 acute angle, 0 right angles, and 2 obtuse angles
  
• C. 2 acute angles, 1 right angle, and 0 obtuse angles
  
• D. 1 acute angle, 1 right angle, and 1 obtuse angle
  

Answer 1

The correct option is A 2 acute angles, 0 right angles, and 1 obtuse angle


$\angle$ A is less than 90 degrees; thus, it is an acute angle.
$\angle$ B is greater than 90 degrees; thus, it is an obtuse angle.
$\angle$ C is less than 90 degrees; thus, it is an acute angle.
Hence, the triangle has 2 acute angles, 0 right angles, and 1 obtuse angle.
