Answer:

18.91 cm

Step-by-step explanation:

Let x represent the height of the flag pole

Tan= opposite/ adjacent

Tan 42°= x/21

x= Tan 42° × 21

= 0.9004 × 21

= 18.91 cm

Hence the height is 18.91 cm

What is the relative size of (how many times as large) a circle's' circumference C to its diameter, d
Pavlova-9 [17]

Answer:

The circumference is pi times larger than the diameter of a circle.

Step-by-step explanation:

The formula of the circumference of a circle is

C = 2(pi)r = (pi)d

C = (pi)d

To find the ratio of the circumference to the diameter, divide both sides of the equation by d.

C/d = pi

The circumference is pi times larger than the diameter of a circle.

F-20f=21 what’s the answer
Virty [35]

\bold{[ \ Answer \ ]}

\boxed{\bold{F \ = \ -\frac{21}{19} }}

\bold{[ \ Explanation \ ]}

  • \bold{Solve: \ f \ - \ 20f \ = \ 21}

-----------------------------------

  • \bold{Add \ Similar \ Elements:f-20f=-19f}

\bold{-19f=21}

  • \bold{Divide \ Both \ Sides \ By \ -19}

\bold{\frac{-19f}{-19}=\frac{21}{-19}}

  • \bold{Simplify}

\bold{F \ = \ -\frac{21}{19}}

\boxed{\bold{[] \ Eclipsed \ []}}
