Answer:
The three angles of the triangle are 41°, 56° and 83°.
Step-by-step explanation:
The three angles of a triangle are given by 2x + 1, x and x + 15.
Now, we know the property of triangle, that 180° is the sum of all the angles of a triangle.
Hence, (2x + 1) + x + (x + 15) = 180°
⇒ 4x + 16 = 180
⇒ 4x = 164
⇒ x = 41°
So, 2x + 1 = 83° and x + 15 = 56°
Therefore, the three angles of the triangle are 41°, 56° and 83°.
