Answer

12. x = 15, y = 21

13. x = 10, M = 37, N = 84, P =59

14. x = 19, R = 43, S = 20, T = 117

15. A = 21, B = 125, C = 34

16. J = 48, K = 57, L = 75

Explanation

12. 6x - 11 + x + 5 + 81 = 180

     7x + 75 = 180

     7x = 105

     x = 15

     4y - 18 + y + 14 + 6*15 - 11 = 180

     5y + 75 = 180

     5y = 105

     y = 21

13. 4x - 3 + 9x - 6 + 6x - 1 = 180

    19x - 10 = 180

    19x = 190

    x = 10

    M = 4*10 - 3 = 37

    N = 9*10 - 6 = 84

    P = 6*10 - 1 = 59

14. R = 2x + 5

    S = x + 1

    T = 7x - 16

    2x + 5 + x + 1 + 7x - 16 = 180

    10x - 10 = 180

    10x = 190

    x = 19

   R = 2*19 + 5 = 43

   S = 19 + 1 = 20

   T = 7*19 -16

15. A = C -13

    B = 4C - 11

   

    c - 13 + 4c - 11 + c = 180

    6c -24 = 180

    6c = 2-4

    C = 34

   A = 34 - 13 = 21

   B = 4*34 - 11 = 125

16. K = J + 9

     L = 2J -21

     j + 9 + 2j - 21 + j = 180

    4j -12 = 180

    4j = 192

    J = 48

    K = 48 + 9 = 57

    L = 2*48 -21 = 75

To find a missing side of a right triangle use the Pythagorean theorem
A2+b2=c2
C is the hypotenuse (long side)
Plug into the equation
11^2+b2=12^2
121+b2=144
So subtract 144-121 to get the missing side you get 23
Take the square root
It will be 4.7
If they want it rounded
X=5
If I had any mistakes in my answer I am sorry but everything should be correct
