Answer:
131 cm
Step-by-step explanation:
formula for surface area of pyramid is
S = (1/3)Bh
but the base ia a square, so B =
S = (1/3)
the pic shows h = 8
but we don't know x
do SohCahToa
sin60 = x/8
x = 8sin60
x = 6.92820323 or 7
plug in numbers
S = (1/3)8
S = 392/3
S = 130.6666667 or 131 cm
Y = 7x + b
2 = 7 + b, b = -5
Y = 7x - 5
