Question

Find the third angle in a triangle when the other two angles are (2a-32)° and (3a+22)°​

Answer 1

(190-5a)°

Explanation:

Sum of internal angles of a triangle equals to 180°

If the third angle is x, then we have:

• (2a-32)°+(3a+22)° +x = 180°
• (5a- 10)° +x= 180°
• x= (180+10-5a)°
• x= (190-5a)°

The third angle is: (190-5a)°
