Step-by-step explanation:
<u>Step 1: Set up</u>
75 + 120 + 90 + ∠4 = 360
<u>Step 2: Solve</u>

- [Subtraction Property of Equality] Subtract 285 on both sides: ∠4 = 75
Answer:
3/10
Step-by-step explanation:
9-6=3
both fractions have the same denominator so they keep it
9/10 - 6/10 = 3/10
<h3>3/10 is also 0.33</h3>
100% - 14% = 86%
86% of what gives you 559
559 * 100 = 55,900/86 = 650
650 students in total
650 - 559 = 91
Solution: 91 students failed
