In the figure below PQ = QR.

What is the value of y?

Select one:
A. 30
B. 40
C. 50
D. 60
E. 70

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.
