If the angles of a triangle form an arithmetic sequence, the middle angle must be the average of the three angles, hence 180°/3 = 60°. The sum of the other two is then 180° -60° = 120°
The largest angle is 120° - 23° = 97°.
_____
The common difference is 37°.
Answer:
y = 33/5 or 6.6
Step-by-step explanation:
7y + 44 = 12y + 11
-11 -11
7y + 33 = 12y
-7y -7y
33 = 5y
Divide both sides by 5
= 33/5 or 6.6
