Answer:
45°, 60°, and 75°
Explanation:
Note:
The sum of the angles in a triangle is always 180°.
For the Question :
if the three angles of the triangle are 3x, 4x, and 5x, then we have the equation:
3x + 4x + 5x = 180°
Combining like terms, we get:
12x = 180
Dividing both sides by 12, we get:
x = 15°
Therefore, the angles of the triangle are:
3x = 3 * 15 = 45°
4x = 4 * 15 = 60°
5x = 5 * 15 = 75°
So, the exact sides of each angle of the triangle are 45°, 60°, and 75° respectively.
