Answer:
d.45 sq.ft
Step-by-step explanation:
Surface are i.e. Total surface area of square pyramid = a^2 + 2al
where a^2 is area of base
a is side of base
l is slant height
by the figure
a=3ft
a^2 = a×a
=3×3
=9ft
l=6ft
Surface area = a^2+2al
=9+2×3×6
=9+36
=45 sq.ft
I would need to see the grapgh
3x =50 2x= 50
because if 3x is 50 and 2x is 50 then you have the 80 degree angle that makes a straight angle which is 180 degrees.
