Question

Two angles of a triangle are 35° and 65°. Find the third angle.​

Answer 1

Answer:

80

Step-by-step explanation:

a+b+c=180

c=180-35-65

c=80

Answer 2

Step-by-step explanation:

━━━━━━━━━━━━━━━━━━━━━━━━

The sum of all angles of a triangle is 180°.

Let a triangle ABC such that A= 35°, B= 45°

⤇A+B+C = 180°

⤇35° + 45° + C = 180°

⤇80° + C = 180°

⤇ C = 180° - 80°

⤇ C = 100°

So, the measure of third angle is 100°
