Answer/Step-by-step explanation:
✔️Find W using the right triangle altitude theorem:
Thus,
W = √(15/2 × 10)
W = √75
W = 8.7 (nearest tenth)
✔️Find J using Pythagorean Theorem:
J² = W² + (15/2)²
J² = 8.7² + (15/2)²
J² = 131.94
J = √131.94
J = 11.5 (nearest tenth)
✔️Find A using Pythagorean Theorem:
A² = W² + (10)²
A² = 8.7² + (10)²
A² = 175.69
A = √175.69
A = 13.3 (nearest tenth)
