emmasim [6.3K]

Answer:

\huge \boxed{ \boxed{ \red{{s \approx \: 10.47}}}}

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • geometry
  • PEMDAS
<h3>tips and formulas:</h3>
  • s =  \frac{\pi {r} \theta}{180}
<h3>given:</h3>
  • r=10
  • \theta = 60
<h3>let's solve:</h3>
  1. \sf sustitute \: the \: value s \: of \:  \theta \: and \: r :  \\  =\frac{\pi \times 10 \times 60}{180}
  2. \sf rediuce \: 60 :  \\  =\frac{\pi \times 10 \times  \cancel{60}  \: ^{1} }{ \cancel{180}  \:  \:^{3} }  \\  =\frac{\pi \times 10}{3}
  3. \sf use \: 3.14 \: for \: \pi :  \\ = \frac{3.14 \times 10}{3}
  4. \sf simplify \: multipication :  \\  =  \frac{31.4}{3}  \\  \approx \: 10.47

Y= 5x + 13 <br> and<br> y= x + 45
arsen [322]

Answer:

x=8 and y=53

Step-by-step explanation:

Given function:

  • y=5x+13
  • y=x+45

Find x:

  • the two equation, the x and are breaked apart..
  • so find a number that they can both equal to together and has the same y.
  • multiply by 8..
  • 5·8=40
  • combine the terms for x and 13
  • 40+13=53
  • since x is 8 then if we add 8 with 45 it should be 53...
  • 8+45=53

y is:

  • this means that y=53.

Therefore, x=8 and y=53..
