Question

One of the angle of a right angled triangle is 40•.Find the

other angle of triangle .​

Answer 1

Answer:

other angle is of 50°

Step-by-step explanation:

Let the three angles be ∠1, ∠2 and ∠3

As ∠1= 40° (Given)

and ∠2 = 90° (given right angled triangle)

Now,

∠1 + ∠2 + ∠3 = 180° (angle sum property of triangle)

40° + 90° + ∠3 = 180°

130° +∠3 = 180°

⇒∠3 = 180°-130°

⇒∠3 = 50°

hence, the other angle is of 50°.
