- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] tan∅ = opposite over adjacent
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
Angle = 35°
Opposite Leg = 3
Adjacent Leg = <em>x</em>
<em />
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [tangent]: tan35° = 3/x
- Multiply <em>x</em>: xtan35° = 3
- Isolate <em>x</em>: x = 3/tan35°
- Evaluate: x = 4.28444
- Round: x ≈ 4.3
Answer 45
Step-by-step explanation: i show my work in case
The area as a function of b is given by

You want to find b such that a(b) = 36.
... (2/3)b^3 +6b = 36
... b^3 +9b -54 = 0 . . . . multiply by 3/2 to clear fractions
A graphing calculator shows this equation to have one real solution at b=3.
The value of b is 3.
= 7/8 − 1/5
= ((7 × 5) − (1 × 8)) / (8 × 5)
= (35 - 8) / 40
= 27/40
= 27/40
SO, 27/40 minutes are NOT spend on instructions.
Hope I helped:P
