Alja [10]

Answer:

The base of the ladder is 2.58 m.

Step-by-step explanation:

Given that,

The angle of elevation for a ladder from the ground is 75°.

The length of a ladder, H = 10 foot

We need to find the distance from the house should you place the base of the latter. Let the base of the ladder is b. Using trigonometry,

\cos\theta=\dfrac{B}{H}\\\\B=H\times \cos\theta\\\\B=10\times \cos(75)\\\\B=2.58\ m

So, the base of the ladder is 2.58 m.

The width of the river = 60m and so Zachary will be able to swim the river without getting tired.

<h3>What is Proportion ?</h3>

When two ratios are equal , the ratio are said to be in proportion.

As given in the question ,

the width of the river has to be determined

Looking at the figure , the triangle formed at the side of the river is a right triangle the hypotenuse will be determined from the Pythagoras theorem

20² +24² = y²

y = 21.2 m

As the corresponding sides are proportional

31.2 : z = 20:50

z = 78.1

The value of the width of the river will be determined by the Pythagoras Theorem

78.1² = 50² + x²

x = 60m

the width of the river = 60m

Therefore Zachary will be able to swim the river without getting tired.
