In triangle $ABC$, the angles $\angle A$, $\angle B$, $\angle C$ form an arithmetic sequence. If $\angle A = 23^\circ$, then what is $\angle C$, in degrees? if u can't understand latex then: In triangle ABC, the angles, angle A, angle B, angle C form an arithmetic sequence. If angle A = 23 degrees, then what is angle C, in degrees?

Step-by-step explanation:

Given that the angles A, B, C in a Triangle form an arithmetic sequence where A=23 degrees.

The nth term of an Arithmetic sequence is given by the formula:

Where:

a=first term

n=number of term

d=common difference

In this case,

The sum of angles in a triangle is 180 degrees. Therefore:

∠A+∠B+∠C=180 degrees

Therefore:

Angle C,
