\huge {\mathfrak{Answer :  }}

we know,

\boxed{\cos( \theta)  =  \dfrac{base}{hypotenuse}}

so,

  • \cos(30)  =  \dfrac{24}{x}

  • \dfrac{ \sqrt{3} }{2}  =  \dfrac{24}{x}

  • x =  \dfrac{24 \times 2}{ \sqrt{3} }

  • x = 8 \sqrt{3}  \times 2

  • x = 16 \sqrt{3}

now,

\boxed{ \tan( \theta) =  \frac{perpendcular}{base}  }

  • \tan(30)  =  \dfrac{y}{24}

  • \dfrac{1}{ \sqrt{3} }  =  \dfrac{y}{24}

  • y =   \dfrac{24}{ \sqrt{3} }

  • y = 8 \sqrt{3}

4.65 x 10 to the 3rd power
yaroslaw [1]

Answer:

(4.65 x 10)^3 = 100,544.625

Step-by-step explanation:

First, multiply 4.65 by 10

46.5

Now multiply this number by itself 3 times

46.5 x 46.5 = 2,162.25

2,162.25 x 46.5 = 100,544.625

So the answer is 100,544.625

In the isosceles trapezoid, m∠S=68∘ .<br><br> What is m∠Q ?
zmey [24]

9514 1404 393

Answer:

  112°

Step-by-step explanation:

Same-side angles of a trapezoid are supplementary.

  m∠P = 180° - m∠S = 180° -68° = 112°

The angles of an isosceles trapezoid match their symmetrical counterparts.

  m∠Q = m∠P

  m∠Q = 112°
