The sum of the angles in a triangle is 180°, If I remember correctly.
Answer: B
Step-by-step explanation:
16:24 students made at least 80% on the test. The question is what is the ratio of students who scored below an 80% to the total number of students. 8:24 would be the right answer, but since it is asking for the answer in the simplest form, it would be 1:3.
