The triangle angle on theorem states the sound of the angles inside a triangle must equal 180° use this serum find the measure of angle C and inside the triangle we have C degrees and then on the other end we have 25°, so the measure of Anglesey would it be 155° 205°, 65° or 55°

Answer 1

The sum of the angles inside a triangle must equal 180°.

We are given that one angle is 25°, and we are looking for the measure of angle C. Let's call angle C x.

So, we have:

25° + x + C = 180°

We know that the sum of the angles in a triangle is 180°, so:

25° + x + C = 180°

Substitute the given angle C for x:

25° + 25° + C = 180°

50° + C = 180°

Subtract 50° from both sides:

C = 130°

Therefore, the measure of angle C is 130°.

So, out of the given options, 65° is the closest answer.
