There are two possible triangles with the measures given for triangle abc. b = 20.2, c = 18.3, c = 38° what are the possible measures of angle b? round your answer to the nearest whole number. a.4° b.4° and 176° c.43° d.43° and 137°

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
