12. Find the value of x. m<1=7x-3 and m<2=5x+17
x=________
m<1=________
m<2=________
13. Find the value of x. m<3=6x+17 and m<4=8x-19
x=________
m<3=________
m<4=________

Answer

  1. To find the value of x, set the expressions for m<1 and m<2 equal to each other because they are vertical angles:

    7x - 3 = 5x + 17

    Solve for x:

    7x - 5x = 17 + 3

    2x = 20

    x = 10

    Now, substitute x back into the expressions for m<1 and m<2:

    m<1 = 7(10) - 3 = 70 - 3 = 67

    m<2 = 5(10) + 17 = 50 + 17 = 67

  2. To find the value of x, set the expressions for m<3 and m<4 equal to each other because they are vertical angles:

    6x + 17 = 8x - 19

    Solve for x:

    6x - 8x = -19 - 17

    -2x = -36

    x = 18

    Now, substitute x back into the expressions for m<3 and m<4:

    m<3 = 6(18) + 17 = 108 + 17 = 125

    m<4 = 8(18) - 19 = 144 - 19 = 125
