Question

Tow acute angles of angled triangle are equal.Find the two angles​

Answer 1

Let the two equal acute angle be x then, sum of all angles of a triangle

∴ x+x+90°

=180°

⇒ 2x+90° =180°

⇒ 2x=180° −90°

⇒ 2x=90°

⇒ x= 2/90°

⇒ x=45°

∴ Two acute ∠s are 45°,45°

Answer 2

Answer:

The two acute angles of a right-angled triangle are equal.

The sum of the angles of the triangle is 180.

If the acute angle is x

Then x+x+90=180

2x+90=180

=> 2x=90

or x=45

Thus the value of two acute angles in right angled triangles will be 45 degrees each.

Step-by-step explanation:

In an equilateral triangle also, all the angles are  60 degrees each.
