Answer:
Perpendicular = Y = 34.64 ft (Approx)
Base = X = 20 ft
Step-by-step explanation:
Given:
θ = 60°
Hypotenuse = 40 ft
Perpendicular = Y
Base = X
Find:
X and Y
Computation:
Sinθ = Perpendicular / Hypotenuse
Sin 60 = Y / 40
Perpendicular = Y = 34.64 ft (Approx)
Cosθ = base / Hypotenuse
cos 60 = X / 40
Base = X = 20 ft

Given:
- The area of a rectangular painting is 7719 cm²
- Width of painting = 83cm
To Find?
Solution:
- Let length of painting be x cm
Using formula:
- Area of rectangle = L × B
Where,
- Length = x cm
- Breadth = 73 cm
→ 7719 = x × 83
→ x = 7719/83
→ x = 93 cm
Hence,
- Length of painting is 93cm
