Final answer:
To find the length of side XY in a right-angled triangle with YZ equaling 4 and assuming angle XYZ is 60 degrees, use the sine function to get XY ≈ 4.62 units.
Step-by-step explanation:
The student is asking how to find side XY in a right-angled triangle, where YZ equals 4 and MX equals 60, which seems like it could be a typo as it is not a standard labeling for parts of a triangle. Assuming MX is meant to represent angle MXZ or angle XYZ, and this angle is 60 degrees because Y is the right angle, you can use the sine function to calculate the length of side XY.
In triangle XYZ, using the sine function:
- sin(MXZ) = opposite/hypotenuse
- sin(60°) = YZ/XY
Therefore:
- XY = YZ / sin(60°)
- XY = 4 / (√3 / 2)
- XY = 8 / √3
- XY ≈ 4.62 (to two decimal places)
So the length of side XY is approximately 4.62 units.
