In triangle ABC, <A is a right angle, and m<B = 45°.
2 answers:
1. The lenght BC is the hypotenuse of the triangle and to find its value, we must apply:
Sin(α)=opposite leg/hypotenuse
The opposite leg is14 ft.
The hypotenuse is BC.
The Angle "α" is 45°.
2. Let's substitute in the formula:
Sin(α)=opposite leg/hypotenuse
Sin(45°)=14/BC
3. When we clear BC, we obtain:
BCxSin(45°)=14
BC=14/Sin(45°)
4. Then, the result is:
BC= 14√2 ft
