Answer:
1 < x < 17
Step-by-step explanation:
9, 8
Third side should be less than 9 + 8 = 17
And it should be greater than 9 - 8 = 1

Answer:
12.9 square yards
Step-by-step explanation:
The base is an equilateral triangle, so we can assume that the three faces have the same dimensions. Each of those face triangles has an area of ...
A = 1/2bh
A = 1/2(3 yd)(2 yd) = 3 yd²
The base area is computed using the same formula and the given height:
A = 1/2(3 yd)(2.6 yd) = 3.9 yd²
Then the total surface area is that of the base and the three faces:
SA = (3.9 yd²) + 3(3 yd²) = 12.9 yd² . . . total surface area
To get the answer you have to add 29.4 and 13.9 and you get 43.3
It is A
