Answer:
360 = x+123+ 90
x = 147
Step-by-step explanation:
The three angles form a circle which is 360 degrees
360 = x+123+ 90
Subtract 123 and 90 from each side
360 -123 - 90 = x
147 = x
The constant proportionality is whats left over

Answer:
Supplementary angles
x = 31
Step-by-step explanation:
Since, (3x + 25)° and 2x° are straight line angles. Therefore they are supplementary angles
(3x + 25)° + 2x° =180°
(5x + 25)° = 180°
5x + 25 = 180
5x = 180 - 25
5x = 155
x = 155/5
x = 31
They are both proportional. 1:4 and 1:15
