Answer: 3 acute angles
and 2 acute angles, 1 obtuse angle
and 2 acute angles, 1 right angle
Step-by-step explanation:
the key is just to imagine it
also you have to know that right angle is 90° acute is less than 90° and obtuse is more than 90°
10% of 1000 is 100. So 3% must be 30. $1000 + 30 = 1030. However, she adds the $50 in the account as well. So 1030 + 50 = $1080
