Answer:
x=6.3m
Step-by-step explanation:
Let the opposite side be y in 2nd triangle.
tan 27° = y/9
=> tan 27° X 9 = y
∴ y = 4.585m ≈ 4.59m
cos 43° = y/x
=> cos 43° = 4.59/x
=> cos 43° X x= 4.59
=> x = 4.59/cos 43°
∴ x = 6.276m ≈ 6.3m (corrected to 1 dp)
One mile equals 5280 feet so
607,200/5280=115
So it’s 115 miles per hour
160
2+2=4
4 x 40= 160
Answer: x>2
x =
f(x)=4
fx=4
÷f on both sides
x=
