hello, can you help me with this?

What is the area of triangle XYZtriangle XYZ to the nearest tenth of a square inch? Use special right triangles to help find the height. Leave your answer in terms of the radical. 

"Show your work." please 

 

The image displays a right-angled triangle labeled XYZ.

- The right angle is located at vertex X.
- The horizontal side, XZ, which is the base of the triangle, has a length of 12 feet.
- Angle YXZ is 60 degrees.
- The vertical side, XY, and the hypotenuse, YZ, are also shown but their lengths are not provided.

Such a triangle is commonly studied in trigonometry and geometry, where you may need to find unknown side lengths or angles using trigonometric ratios and the Pythagorean theorem. This triangle appears to be a 30-60-90 triangle, a special type of right-angled triangle that has side ratios of 1 : √3 : 2. 

In this case, since angle XYZ is 30 degrees and angle YXZ is 60 degrees, the leg opposite the 30-degree angle (XZ) is half the hypotenuse (YZ), and the leg opposite the 60-degree angle (XY) is √3 times the shorter leg (XZ). Given that XZ is 12 feet, XY will be 12√3 feet, and YZ, the hypotenuse, will be 24 feet. 

This is a foundational concept in trigonometry, illustrating the relationship between the angles and side lengths in right-angled triangles.
