Question

In ∆ABC, ∠B= 67°, ∠C = 84°. Find ∠A.​

Answer 1

Answer:

this question answer is 29 .

Answer 2

Given: ∠B = 67° and ∠C = 84°

Solution:

In ∆ABC,

∠A + ∠B + ∠C = 180° [Sum of all interior angles is equal to 180° or Angle Sum Property]

» ∠A + 67° + 84° = 180°

» ∠A = 180° - 151°

» ∠A = 29°

So, The ∠A is 29°.
