Answer:
54 yd²
Step-by-step explanation:
The surface area of the prism is the sum of the areas of its faces. Opposite faces have the same area, so we can write the formula as ...
SA = 2(LW +WH +LH) = 2(LW +H(L +W))
Filling in the numbers, we have ...
SA = 2(6·3 +1(6 +3)) = 2(18 +9) = 54 . . . . square yards
The area is 54 square yards.
Answer:
x = 54°
Step-by-step explanation:
90° = 2x-18°
90° + 18° = 2x
108° = 2x
x = 54°
Answer:
72
Step-by-step explanation:
If BFD is a right angle and it gives you CFD that means that you do 90 - 72 to find CFB cause it 90 all togther
CFB = 18 deg
now it also tells us CFA is a 90 deg angle so we do the same thing
90 - 18 = 72
Answer:
x=3130/3
Step-by-step explanation:
3,125 = 5-10 + 3x
5-10+3x=3125
3x-5=3125
3x-5+5=3125+5
3x=3130
3x/3 = 3130/3
x=3130/3
I hope this helps!
