Question

in triangle ABC if measure angle A=measure angle B=70 what is measure angle C.​

Answer 1

Answer:

40°

Step-by-step explanation:

Sum of all angles in triangle is 180.

∠A + ∠B + ∠C = 180

70° + 70° + ∠C = 180

∠C  = 180  - 140 = 40°

Answer 2

Answer: 40°

Step-by-step explanation:

Given, ∠A=∠B=70°

In triangle ABC,

∠A+∠B+∠C=180°   (Angle Sum Property)

⇒70°+70°+∠C=180°

⇒140°+∠C=180°

⇒∠C = 180° - 140°= 40°
