Question

please answer this
find the unknown angle ​

Answer 1

Answer:

1st angle = 17°

2nd angle = 38°

We know that sum of angles of a triangle is 180°

3rd angle = 180-(17+38)

= 180-55 = 125°

Answer 2

Answer:

Let the unknown angle be x

We know that,

Sum of angles of a triangle = 180°

17° + 38° + x = 180°

x =180°- 55°

x = 125°

Hence, the unknown angle is 125°
