Idon't ! a) write an equation (eq that represents the diagram. b)find the value for x. c) find the missing angle measures.

A) The diagram is apparently supposed to be interpreted as showing the measures of two linear angles, that is, angles whose sum is 180°. The equation shows the sum of the angles is 180, so is ...
   (x - 13) + (2x +1) = 180

B) Simplify the expression, add 12, and divide by 3 to find the value of x.
   3x -12 = 180
   3x = 192
   x = 64

C) Fill in the value of x in the expressions for the angle measures.
   ∠ = 64 - 13 = 51
   ∠ = 2×64 +1 = 129

Deja qué x = longitud6(x) = 48cm^2divide por 6: x = 8la área de longitud es 8 cm.
