Answer:
(C) 1/2
Step-by-step explanation:
If 4s is 2 more than 4t, then:
- 4s = 2+ 4t
- 4s - 4t = 2
- 4s/4 - 4t/4 = 2/4
- s - t = 1/2
(C) is the answer
2x + 2x + x = 180°
5x = 180°
x = 36° (C)
smallest triangle 5.7/11,
medium triangle 11/x
5.7/11=11/x
x=11*11/5.7≈21.2 (longer leg of the medium triangle)
difference between 6 and 5.7 is 6-5.7=0.3 ,
screen going to be 0.3 feet less, than leg of the medium triangle that was found
21.2-0.3=20.9 ft
