Question

an acute angle of a right angle triangle is 33 degree find its acute oother angle​

Answer 1

Answer:

1st angle is 90 degree

2nd given is 33 degree

sum of angle of triangle is 180

so other acute angle is 180-90-33

180-123=57 degree

Answer 2

Step-by-step explanation:

Given:-

An acute angle of a right angle triangle is 33°

To find:-

Find its acute other angle ?

Solution:-

Let the other acute angle be X°

Given that

An acute angle of a right angled triangle= 33°

Since it is a right angled triangle,

One angle must be 90°

We know that

The sum of all angles in a triangle is 180°

=> 90°+33°+X° = 180°

=> 123° + X° = 180°

=> X° = 180° - 123°

=> X° = 57°

(or)

Since one angle must be 90°

The other two acute angles are complementary angles.

Therefore, 33°+X° = 90°

=> X° = 90° - 33°

=> X° = 57°

The other acute angle = 57°

Answer:-

The required other acute angle of the right angled triangle is 57°

Used formulae:-

Angle Sum Property:-

• The sum of all angles in a triangle is 180°

Complementary angles:-

• The sum of two angles is equal to 90° then they are called Complementary angles.
