Answer:
Option 2 ⇒ 55° , 45° , 80°
=====================================
Step-by-step explanation:
The acute triangle is a triangle with three acute angles (less than 90°)
Check the given options:
First option is wrong ⇒ one of the angle = 100° > 90°
Second option correct ⇒ we have 3 angles < 90°
Third option is wrong ⇒ one of the angle = 90°
Fourth option is wrong ⇒ one of the angle = 150° > 90° , beside that the sum of three angles not equal to 180°
So, the answer is Option 2 ⇒ 55° , 45° , 80°
