Given: Each of two equal angles of a triangle is twice the third angle.
To find: The angles of the triangle.
⠀⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀⠀⠀⠀⠀⠀⠀⠀
Let the third angle be x.
⠀⠀⠀
- Each of two equal angles of a triangle is twice the third angle.
⠀⠀⠀⠀
⠀⠀⠀
⠀⠀⠀⠀
⠀⠀⠀
- Sum of all angles of the triangle is 180°.
⠀⠀⠀
Therefore,
⠀⠀⠀
⠀⠀⠀
⠀⠀
⠀
- First angle, x = 36°.
- Second & third angle, 2x = 2(36) = 72°.

Answer:
Given :-
- Each of two equal angles of a triangle is twice the third angles.
To Find :-
- What is the angles of the triangle.
Solution :-
Let, the first angles be x
And, the second angles be 2x
And, the third angles will be 2x
As we know that,
According to the question by using the formula we get,
⇒
⇒
⇒
⇒
➠
Hence, the required angles are,
✧ First angles = x = 36°
✧ Second angles = 2x = 2(36°) = 72°
✧ Third angles = 2x = 2(36°) = 72°
The angles of a triangle is 36°, 72° and 72° respectively.
