- [Right Triangles Only] tan∅ = opposite over adjacent
Step-by-step explanation:
<u>Step 1: Identify</u>
Opposite Leg of <em>x</em> = 12
Adjacent Leg of <em>x</em> = 15
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [tangent]: sinx° = 12/15
- Trig inverse: x° = sin⁻¹(12/15)
- Evaluate: x = 53.1301°
- Round: x ≈ 53°

Answer:
≈44.44%
Step-by-step explanation:
≈44.44%
To solve this, we can use a simple proportion.
Assuming 18 = 100%...
Then, using cross multiplication...
Now divide 18 from both sides.
x ≈ 144.44
Now subtract 100 from ≈144.44, leaving us with
≈44.44%
