- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] sin∅ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
Angle = 35°
Opposite Leg = <em>x</em>
Hypotenuse = 20
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [sine]: sin35° = x/20
- Isolate <em>x</em>: 20sin35° = x
- Evaluate: 11.4715 = x
- Rewrite: x = 11.4715
- Round: x ≈ 11.5
Yes. 10/4=2.5 and 15/6=2.5 as well
Answer:
Step-by-step explanation:
9x - 6y = 42
5x + 6y = 42
14x = 84
x = 6
30 + 6y = 42
6y = 12
y = 2

Answer:
the interquartile range is the Q3-Q1 where Q3 is 75th percentile and Q1 is the 25th percentile.
so the total count is 20 so 25 percentile is 25% of 20 =5 and 75th percentile is 75% of 20 = 15 and since the number are already arranged in order we just pick the 15th number-5th number thus, our answer is
12-6 = 6
