x = 180 - 118 ( linear angles)
x = 62
62+62+y = 180
y = 56
Answer:
C
Step-by-step explanation:
I'm just guessing
Given:
Side length of base = 8
Slant height = 6
To find:
The surface area of the square pyramid.
Solution:
Surface area:

where A is the area of base
p is the perimeter of base
s is the slant height
Area of base (A) = 8 × 8
= 64
Perimeter of base(P) = 4 × 8
= 32
Substitute these in the formula:



The surface area of the square pyramid is 160 unit².
