- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] cosθ = adjacent over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
Angle θ = 45°
Adjacent Leg = 25
Hypotenuse = <em>x</em>
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in variables [cosine]:

- [Multiplication Property of Equality] Multiply 25 on both sides:
