Answer:

  • 12. x = 6, side = 83
  • 13. x = 18, side = 29
  • 14. x = 11, sides = 74, 74 and 37
  • 15. x = 23, sides = 95, 95 and 108

Step-by-step explanation:

<em>11 is incomplete, can't solve</em>

12

<u>The triangle is equilateral, so all sides are equal, using one pair to find x:</u>

  • 13x + 5 = 17x - 19
  • 17x - 13x = 5 + 19
  • 4x = 24
  • x = 6

<u>Each side is:</u>

  • 13*6 + 5 = 78 + 5 = 83

13.

<u>Sides are equal as triangle is equilateral</u>

  • QR = 2x - 7
  • RS = 5x - 61
  • QS = x + 11

<u>Finding x by comparing two sides</u>

  • 2x - 7 = 5x - 61
  • 5x - 2x = 61 - 7
  • 3x = 54
  • x = 18

<u>Sides are equal</u>

  • 18 + 11 = 29

14.

<u>Equal sides of isosceles triangle:</u>

  • CD = DE
  • 9x - 25 = 6x + 8
  • 9x - 6x = 8 + 25
  • 3x = 33
  • x = 11

<u>Sides are</u>

  • CD = DE = 9*11 - 25 = 99 - 25 = 74
  • CE = 10*11 - 73 = 110 - 73 = 37

15.

<u>Equal sides of isosceles triangle WXY, WX = WY</u>

  • WX = 4x + 3
  • WY = 7x - 66
  • XY = 5x - 7
  • 4x + 3 = 7x - 66
  • 7x - 4x = 3 + 66
  • 3x = 69
  • x = 23

<u>Sides are:</u>

  • WX=WY = 4*23 + 3 = 95
  • XY = 5*23 - 7 = 108

kvasek [131]
The slant would be greater than the height because it is the hypotenuse and it is always greater than the legs.

R/3+2=21 solve for r
olchik [2.2K]

Answer:

r=63

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    r/3-(21)=0             r

Simplify   —

           3

r    

 — -  21  = 0

 3     2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  3  as the denominator :

         21     21 • 3

   21 =  ——  =  ——————

         1        3  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
