Question

Q # 30 in the given right triangle,find the missing length

Answer 1

Use the Pythagoras theorem to find the unknown side of the right triangle,

c²=a²+b²

c² = 17²+11²

= 289+121
=410

c = √410
=20.248 ft

To the nearest tenth,
Answer = 20.2 ft

Answer 2

apply the Pythagorean Theorem: a² = b² + c²
Where a is the hypotenuse , b and c are legs of the right triangle
The missing side is the hypotenuse
∴ a² = 11² + 17² = 410
∴ a = √410 ≈ 20.2 ft

The correct answer is option 4
