Georgia [21]

Answer:

(1)55.5 feet

(2)7.5 feet

Step-by-step explanation:

<u>Question 1</u>

The diagram is attached below.

Using Trigonometric ratio

$\tan 48^\circ = \dfrac{h}{50} \\h=50 \times \tan 48^\circ\\h=55.5$ feet (to the nearest tenth)$

The height of the house is 55.5 feet to the nearest tenth.

<u>Question 2</u>

In the diagram, we are required to find the distance the bird must fly to be directly above the fish. This has been represented by x.

Using Trigonometric ratio

$\tan 15^\circ = \dfrac{2}{x} \\x \tan 15^\circ=2\\x=2 \div \tan 15^\circ\\x=7.5 $ feet (to the nearest tenth)$

The distance the bird must fly to be directly above the fish is 7.5 feet.
