Greeley [361]

Answer:

See explanation

Step-by-step explanation:

(4)

Using the sine ratio in  the right triangle

sinΘ = \frac{opposite}{hypotenuse} = \frac{7}{9}, thus

Θ = sin^{-1}(\frac{7}{9}) ≈ 51.1°

(5)

Using the tangent ratio in the right triangle

tanΘ = \frac{opposite}{adjacent} = \frac{4}{5}, thus

Θ = tan^{-1}(\frac{4}{5}) ≈ 38.7°

A new park was designed to contain two circular gardens. Garden A has a diameter of 50 m, and garden B has a diameter of 70 m. T
Nastasia [14]

Answer:

5,811.95\  m^2 of fabric.

Step-by-step explanation:

-The amount of fabric needed is equivalent to the  area of the two gardens.

-We calculate the combined areas as:

A=A_s+A_b\\\\=\pi r^2+\pi R^2\\\\=\pi(25^2+35^2)\\\\=1850\pi \ m^2\\\\=5811.95\ m^2

Hence, 5811.95 sq meters of fabric will be needed to cover the area of both gardens.
