Final answer:
To construct triangle XYZ, draw a line segment XY of length 6.7 cm. Then, draw a circle centered at X with a radius of 6.9 cm. Connect the two points where the circle intersects XY to form the triangle XYZ.
Step-by-step explanation:
To construct triangle XYZ with given side lengths, we start by drawing a line segment XY of length 6.7 cm. Then, we draw a circle centered at X with a radius of 6.9 cm. Next, we connect the two points where the circle intersects XY to form the triangle XYZ. The length of YZ is 5.8 cm.
