Answer:

Yes

Step-by-step explanation:

Multiplicative Inverse of rational number:

       When we multiply a rational number and its multiplicative inverse, we get 1

     \sf -5 \dfrac{2}{3}=\dfrac{-17}{3}

  Now,multiply this with (3/-17)

          \sf \dfrac{-17}{3}*\dfrac{3}{-17} = 1

So, -5 2/3  is the multiplicatice inverse of 3/-17

Cerrena [4.2K]

Answer:

Height of flag pole to the nearest foot is 43 feet

Step-by-step explanation:

In the diagram we have flag pole AB and C is the point on the ground.

It is given that angle of depression is 30°

and the distance of the point C from the base B is 75 feet

so we have

BC= 75 feet  

∠C = 30°

AB= h feet

now in right ΔABC

tan C = \frac{opposite \ side }{base} \\tan C=\frac{AB}{BC}

now we plug AB= h , ∠C= 30° and BC =75

tan 30= \frac{h}{75}

75 tan30 = h            ( multiply both sides by 75)

h= 75 tan 30 =75 (0.5773)\\ h= 43.3 feet\\

Height of flag pole to the nearest foot is

h= 43 feet
