Answer:
One angle = x = 55°
Second angle = x = 55°
Two angles = 2x = 110°
Step-by-step explanation:
One angle = x
Second angle = x
Two angles are equal = 2x
Third angle = 70°
The sum of three angles = 180°
70 + 2x = 180
2x = 180 - 70
2x = 110
x = 110/2
x = 55
One angle = x = 55°
Second angle = x = 55°
Two angles are equal = 2x = 110°
Check ⇒
One angle = x = 55°
Second angle = x = 55°
Two angles are equal = 2x = 110°
Third angle = 70°
The sum of three angles = 180°
55° + 55° + 70° = 180°
180° = 180°
L.H.S = R.H.S
Hence, verified.
The answer is correct.
