Question

triangle ABC is right angled at B if angle A is equal to 30 degrees then find angle C​

Answer 1

angke ABC 8s a right angled triangle.

<A+Angle B + angleC =180°

30°+90°+angle A=180°

189-120=angle C

angle C = 60°

Answer 2

Answer:

60°

Step-by-step explanation:

The sum of angles of a triangle is always (considering Euclidean geometry to be valid, of course) 180°.

So, ∠A + ∠B + ∠C = 180°.

But it is given that ∠A = 30°, and that ∠B is a right angle, that is, it is 90°.

Putting these values, we get:

30° + 90° + ∠C = 180°.

Or, ∠C = 60°.

Note that there are way too many approaches to this problem and that this was, perhaps, just one or two of them, IYKWIM.
