The net of a square pyramid is shown below. What is the total surface area of the square pyramid in square meters?

A= 432 m 2

B= 756 m 2

C= 504 m2

D= 864 m 2

i got 86 for this

hope this !

if you need an explanation just ask

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
