Triangles ABC and LMN are congruent according to which of the following congruence criteria? O Angle Side Angle congruence criteria
O Side Side Angle congruence criteria
Side Angle Side congruence criteria
O Side Side Side congruence criteria

Step-by-step explanation:

As per diagram, the triangles have 3 congruent sides:

So they are congruent by SSS criteria

14

step-by-step explanation:

14 x 3 = 42

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
