Answer:
12.68
Step-by-step explanation:
76 degrees /2 = 38
Half the width of 15m forms the lower side of the triangle: 7.5 m
sin(38) = 7.5/h
=12.1820
12.18+.5
12.68
Let b and h represent the length of the side of the base and the slant height, respectively. Then the total surface area is
A = b² + 4*(1/2)bh
A = b² +2bh
Substituting the given numbers, you have
336 = 12² +2·12·h
192 = 24h . . . . . . . . . subtract 12² = 144
8 = h . . . . . . . . . . . . . divide by 24
The slant height is 8 inches.
