Two angles are supplementary if the sum of their measures is 180. If one angle’s measure is 45 more than 3 times the other angle , what are the measures of each angle?
1 answer:
Assuming the two angles are supplementary, the angle measuring x is equal to 33.75, and the angle measuring 3x+45 is equal to 146.25.
Step-by-step explanation:
x+(3x+45)=4x+45=180
4x+45=180
-45 -45
4x=135
÷3 ÷3
x=33.75
3x+45=146.25
