Answer:
Step-by-step explanation:
xº=yº=90º they are perpendicular to each other.
51º+zº=180 angle in a straight line
zº=180-51
zº=129º
the perimeter of each side is 5 so the answer is 20

Answer: A cone with height 3 and radius 1
Step-by-step explanation:
Hi, searching I found the image for the question, attached down below.
By rotating the triangle about line m, a cone with height 3 and radius 1 is produced.
Solid 3d objects are produced by rotating a 2d figure around a straight line that lies in the same place.
in our case, if we rotate the triangle around the line, the vertices in touch with the line m remains stationary, while the remaining vertex follows the path of a circle, creating a cone.
