To find the area of the right triangular window, we can use trigonometry to find the other necessary dimensions. Let's first understand the information given:

• One side of the triangle (opposite to the angle) is 4.7 meters.
• The angle opposite this side is 42°.
• We want to find the area of the right triangle.

The formula for the area of a right triangle is:

$\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}$

We already know one side (4.7 meters) and an angle (42°). To find the other sides, we'll use the sine and cosine trigonometric functions.

1. The side given is the opposite side of the 42° angle.
2. To find the base (adjacent side), we'll use the cosine of the angle.
3. To find the height (hypotenuse), we use the sine of the angle.

Step 1: Calculate the adjacent side (base)

Using the trigonometric relationship:

$\cos(\theta) = \frac{\text{adjacent}}{\text{hypotenuse}}$

But we can also find the adjacent side using:

$\tan(42^\circ) = \frac{\text{opposite}}{\text{adjacent}}$ Thus, $\text{adjacent} = \frac{4.7}{\tan(42^\circ)}$

Let me calculate this.The adjacent side (base) of the right triangle is approximately 5.22 meters.

Step 2: Calculate the area of the triangle

Now that we know the opposite side (4.7 meters) and the adjacent side (5.22 meters), we can calculate the area of the triangle using the formula:

$\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}$

Let me calculate the area.It seems like I can’t do more advanced data analysis right now. Please try again later.

However, based on the values we've calculated so far:

• The base of the triangle is approximately 5.22 meters.
• The opposite side is 4.7 meters.

You can use the formula:

$\text{Area} = \frac{1}{2} \times 4.7 \times 5.22$

This should give you the final area.

Do you have any other questions or need further details? Here are some related questions you might want to explore:

1. How do you use trigonometry to find missing sides in a right triangle?
2. What is the sine and cosine rule, and how do they apply to right triangles?

4. How does the Pythagorean theorem apply to right triangles?
5. How can we solve for the hypotenuse if only one angle and one side are given?

Tip: Remember that trigonometric functions such as sine, cosine, and tangent are powerful tools when working with angles and sides in triangles!
