Answer:
35 cm
Step-by-step explanation:
Perimeter is the sum of all edges of the given figure.
Given: the perimeter of the base of the regular triangular pyramid is P = 16.5 cm and the perimeter of a lateral face is 18.5 cm.
To find: sum of all edges of this pyramid
Solution:
sum of all edges of this pyramid = perimeter of the base of the regular triangular pyramid + perimeter of a lateral face = 16.5 + 18.5 =35 cm
Add up all the hours so 5+2+1=8
Math would be 2:8 and I think u can simply it to 1:4
Hope it helps
Using the sum of interior angles equation;
(n-2)180=sum
(n-2)180=2340
n-2=2340/180
n-2=13.5
n=13.5+2
n=15.5
However, the problem is that a polygon cannot have "half" as side. Therefore, there might be a problem in the question or there is no solution to such a question.
