Consider carmen’s plans. angles carmen used her knowledge of angle relationships to find the value of x in the diagram. what is the value of x? x = 5 x = 9 x = 13 x = 16if ur smart the answer is 9

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
