Answer:
30°
Step-by-step explanation:
Here,
The sum of three angles of a triangle is 180°.
The given angles of a triangle are 3x , x/2 and 5x/2
By question,
3x + x/2 + 5x/2 = 180° ( angle sum property of a triangle )
→ 6x + x + 5x / 2 = 180°
→ 12x / 2 = 180°
→ 12x = 180° × 2
→ 12x = 360°
→ x = 360° / 12
→ x = 30°
Hence, the value of the x is 30°
