Answer: C
Step-by-step explanation:
Use proportion:
360:100=x=25
100x=25*360
x=360/4
x=90
cosine ( CAH) = Adjacent/ hypothenus
cos9 = x/ 2
let x represent the horizontal distance
2 cos 9 = x
x = 2 (0.98768834)
x = 1.975
x = 1.97
therefore the horizontal dstance jade covers is 1.97km
8/(2-√ 12) Both sides multiplied by (2+√ 12)
16+8√ 12/4-12
-(16+8√ 12)/8
The new denominator is 8 and the fraction has a negative sign
Answer:
Step-by-step explanation:
3x + 18 = 4x + 7
18 - 7 =4x - 3x
11 = x
x= 11
