Step-by-step explanation:2.25 miles per hour = 3.621 kilometers per hour
Formula: multiply the value in miles per hour by the conversion factor '1.609344'.
So, 2.25 miles per hour = 2.25 × 1.609344 = 3.621024 kilometers per hour.
The value of b would be 47
Answer:
x = 8.3 is the value of x.
Step-by-step explanation:
Given:
Let Δ ABC be a Right angle Triangle at ∠ C = 90°
AB = x
BC = 6
m∠ B = 44°
To Find:
x = ?
Solution:
We apply Cosine Rule
{tex}\cos B = \frac{\textrm{side Adjacent to angle B}}{Hypotenuse} \\{/tex]
Substituting the given values we get
![\cos B = \frac{BC}{AB}\\\\\cos 44 = \frac{6}{x}\\\\0.719=\frac{6}{x}\\\\\therefore x=\frac{6}{0.719} \\\\\therefore x=8.3......(nearest\ tenth)](https://tex.z-dn.net/?f=%5Ccos%20B%20%3D%20%5Cfrac%7BBC%7D%7BAB%7D%5C%5C%5C%5C%5Ccos%2044%20%3D%20%5Cfrac%7B6%7D%7Bx%7D%5C%5C%5C%5C0.719%3D%5Cfrac%7B6%7D%7Bx%7D%5C%5C%5C%5C%5Ctherefore%20x%3D%5Cfrac%7B6%7D%7B0.719%7D%20%5C%5C%5C%5C%5Ctherefore%20x%3D8.3......%28nearest%5C%20tenth%29)
The value of x is
x = 8.3
