Is the question asking about what is the meaning of Trepidation?
The equation for two supplementary angles is m∠A + m∠B = 180.
We also know that m∠A = 2x + 3, and m∠B = 3x - 223.
So, all we have to do is input both of the angles' values in:
(2x + 3) + (3x - 223) = 180
Simplify:
5x - 220 = 180
Add 220 to both sides:
5x = 400
x = 80
Now that we know the value of x, we just have to input it into the angles:
m∠A = 2(80) + 3 = 160 + 3 = <em><u>163°</u></em>
m∠B = 3(80) - 223 = 240 - 223 = <em><u>17°</u></em>
