An obtuse angle is formed by two adjacent angles, (x−5)° and (3x)°. If the resulting angle is 107°, what is the angle measure of each of the two unknown angles? Round to the nearest whole number.
A: 20° and 87°
B: 28° and 79°
C: 23° and 84°
D: 32° and 75°

B: 28° and 79°
As expected, the bot is wrong again.
x-5 + 3x = 107
4x = 112
x = 28
so the angles are 23° and 84°
x-5 + 3x = 107
4x = 112
x = 28
so the angles are 23° and 84°
Haven't you beaten this type of problem to death yet? Surely by now you know how to solve them.
