Answer:  x = 2.65, y = 3.81

Step-by-step explanation:

          ABC similar to PQR

1) Find the ratio of corresponding sides

2) Use that ratio to find values for x & y

        1) Side AB = 2.76cm & Side PR = <em>y</em><em> </em>cm

             Side BC = <em>x</em> cm & Side RQ = 3.66 cm

         Side CA = 3 cm & Side QP = 4.14 cm (both lengths given)    

Can match 3 to 4.14 & ratio of sides in ABC to PQR= 3 /4.14

Length of sides ABC = 3/4.14 times the length of sides PQR

           2)  x = (3 / 4.14) * 3.66 = 2.65

            Now solve for y, ABC to PQR:  2.76 = (3 / 4.14) (<em>y </em>)

<em>equality property</em> (both sides) & inverse operation to isolate <em>y : </em> .               2.76 ÷ (3 / 4.14) = (3 / 4.14 ) ÷ (3 / 4.14) (<em>y</em><em>)</em>

              2.76 * (4.14 / 3) =  3 / 4.14 * (4.14 / 3) (<em>y</em><em>)</em>

                     (2.76 * 1.38 ) =  3.81  = <em>y</em>

<em></em>

Answer:

2x - 10 = 10 - 3x

Simplifying

2x + -10 = 10 + -3x

Reorder the terms:

-10 + 2x = 10 + -3x

Solving

-10 + 2x = 10 + -3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3x' to each side of the equation.

-10 + 2x + 3x = 10 + -3x + 3x

Combine like terms: 2x + 3x = 5x

-10 + 5x = 10 + -3x + 3x

Combine like terms: -3x + 3x = 0

-10 + 5x = 10 + 0

-10 + 5x = 10

Add '10' to each side of the equation.

-10 + 10 + 5x = 10 + 10

Combine like terms: -10 + 10 = 0

0 + 5x = 10 + 10

5x = 10 + 10

Combine like terms: 10 + 10 = 20

5x = 20

Divide each side by '5'.

x = 4

Simplifying

x = 4

Find the length of the arc.
Arte-miy333 [17]
  • radius=r=7in
  • Angle=135°

We know

  • Length if arc=L

\boxed{\sf L=\dfrac{\theta}{360}\times 2πr}

\\ \sf\longmapsto L=\dfrac{135}{360}\times2π(7)

\\ \sf\longmapsto L=\dfrac{27}{72}\times 14π

\\ \sf\longmapsto L=\dfrac{27}{36}\times 14π

\\ \sf\longmapsto L=\dfrac{9}{12}\times 7π

\\ \sf\longmapsto L=\dfrac{63π}{12}

\\ \sf\longmapsto L=\dfrac{21π}{4}in
