Answer:
The length of the arc GH is approximately 3.14 meters (or π)
Step-by-step explanation:
The length of an arc whose measure equals the measure of the central angle Ф and the radius of the circle r is:
Let us solve the question using the rule above
∵ The measure of arc GH is 30°
∴ Ф = 30°
∵ The radius is 6 meters
∴ r = 6 meters
→ Substitute them in the rule above
∵ L = (30° ÷ 360°) × 2π × 6
∴ L = × 12π
∴ L = π
→ Use π ≈ 3.14
∴ L ≈ 3.14
∴ The length of the arc GH is approximately 3.14 meters (or π)

Hi,
So we have g(x) = 4√(x). We're looking for g(45). Think of it like this: whatever number is in the place of x in g(x), just place that number AS x.
Therefore, we have :
g(45) = 4√(45) ⇒ (4) × (√(45)) ⇒ (4)(3√(5)) = 12√(5).
-Hope this helps!
Answer:
Yes it is.
Step-by-step explanation:
For a triangle to be a right angled triangle, it needs to verify the pythagoras theorem which is
h² = p² + b²
where h is the longest side.
So,
15² = 12² + 9²
225 = 144 + 81
225 = 225
which is true.
So the triangle is a right angled triangle.
