Find the length of side AC. Give your answer to 1 decimal place.

The length of AC is 17.3 cm

Step-by-step explanation:

Given,

In the fig: AB = 7 cm and ∠ABC= 68°

To find the length of AC

Formula

tanθ =

Here,

AC is the perpendicular

AB is the base and θ = 68°

So,

tan 68° =

or, AC = tan 68°×AB

= 17.3 (approx)

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
