Question

In ∆ABC,if <B=75°and <C=50° find <A​

Answer 1

Answer:

angle A is 55°.

Step-by-step explanation:

sum of all angles is 180°.

so,

<A+<B+<C=180°

- 75° +50°+ <A=180°

<A= 55°

Answer 2

Answer:

In ∆ABC,

if ∠B=75°

∠C=50°

∠A​ = ?

Since the interior angle of the triangle is 180° so the equation will we

180° = ∠A + ∠B + ∠C

180° = ∠A + 75° + 50°

180° = ∠A + 125°

180° - 125° = ∠A

55° = ∠A

Thus, ∠A = 55°
