Solve for the value of n.pls help I will give brainliest + 34 points!
2 answers:
90+44+(3n-5)=180
134+(3n-5)=180, subtract 134 from both sides
3n-5=46
3n=51
n=17
To check: 90+44+(3x17-5)=180
9514 1404 393
Answer:
n = 17
Step-by-step explanation:
The angle sum theorem tells you the angles add up to the linear angle of 180°.
(3n -5)° + 90° +44° = 180°
3n + 129 = 180 . . . . . . . . . . collect terms
3n = 51 . . . . . . . . . . . . subtract 129
n = 17 . . . . . . . . . . divide by 3
