Kamila [148]3 years ago

Answer:

AC ≈ 5.3 ( to the nearest tenth )

Step-by-step explanation:

Using the cosine ratio in the right triangle.

cos68° = \frac{adjacent}{hypotenuse} = \frac{AB}{AC} = \frac{2}{AC}

Multiply both sides by AC

AC × cos68° = 2 ( divide both sides by cos68° )

AC = \frac{2}{cos68} ≈ 5.3

Answer:

5.3

Step-by-step explanation:

Cos(68) = adjacent/hypotenuse

Cos(68) = 2/AC

AC = 2/cos(68)

AC = 5.3389343253

AC = 5.3

Jim ran 15 miles in 5 days. At this rate, how many days will it take Jim to run 165 miles?
AleksAgata [21]

Answer:

55 days

Step-by-step explanation:

Given

Jim ran 15 miles in 5 days

no. of miles ran in 5 days = 15 miles

dividing LHS and RHS by 5

no. of miles ran in 5/5(=1) days = 15/5 miles = 3 miles

no. of miles ran in 1 day =  3 miles

let the no. of days taken to run 165 miles be x   ----A

No of miles ran in x days = x*no. of miles ran in 1 day = 3x miles

thus,  From A

3x  = 165

x = 165/3 = 55

Thus, it took 55 days for JIM to run 165 miles
