Answer:
x = 7.99 cm
Step-by-step explanation:
By applying cosine rule in the given triangle,
AC² = AB² + BC² - 2(AB)(AC)cosC
Substitute the measures of the sides and the angle in this formula,
x² = 6² + 10² - 2(6)(10)cos(53°)
x² = 36 + 100 - 72.217
x² = 63.782
x = √(63.782)
Y=25-4x
Y means the distance Jordan still has to walk after x hour
depending on the form of how your question is actually written .. The answer will either be :
x= -1
or
There are no values of x that make the equation true. No solution.
Hope this helps
