Question

In a right-angled , two angles are equal. find the angles.​

Answer 1

Answer:

1st angle= 90°

2nd angle= 45°

3rd angle= 45°

Step-by-step explanation:

As it is a right angled triangle, 1st angle will be of 90°.

Also, there are 2 equal angles,

∴the other 2 angles are equal.                  (there cannot be 2 right angles)

∴the other angles are 45° each

Answer 2

Answer :

›»› The angles of a right angled triangle is

Given :

• In a right angled triangle two angles are equal.

To Find :

• The all angles of a triangle = ?

Solution :

Let us assume that, the two angles are equal isin a triangle two angles are "x".

As it is given that, in a right angled triangle two angles are equal.

→ x, x.

As we know that

The sum of all three angles of a triangle is 180°.

→ x + x + 90 = 180

→ 2x + 90 = 180

→ 2x = 180 - 90

→ 2x = 90

→ x = 90/2

→ x = 45

Therefore,

The angles of a triangle will be,

• x = 45°.
• x = 45°.

Hence, the angles of a triangle is 45°, 45°, and 90° respectively.

Verification :

The sum of all three angles of a triangle is 180°.

→ 45 + 45 + 90 = 180

→ 90 + 90 = 180

→ 180 = 180

Clearly, LHS = RHS.

Here, both the conditions satisfy, so our answer is correct

Hence Verified !
