Question

One of the actue angles of right angled triangle is 57°, find the other actue angles​

Answer 1

Answer:

One of the acute angles of a right angled triangle is 55°. What will the other acute angle will be?

Simply we can use the angle sum proprerty of triangle .

For a given triangle the sum of all the three interior angles is 180 degrees.

So let us say the angles are A, B , and C.

So A is given 90 degree .

B is given 55 degree.

We have to find the third angle that is C.

A + B + C = 180

55 + 90 + C =180

145 + C = 180

C = 180 - 145

C = 35 degree is the answer.

Answer 2

Answer:

one acute angle = 57°

The other side is 90° as it is an right angled triangle

A+B+C = 180° ( sum angle of property )

90°+57°+C = 180°

147°+C = 180°

C = 180°-147°

C = 33°
