Answer:
The value of x is 28°
Step-by-step explanation:
Here, In a given fugue, a = 40°
We know that, A straight angle is an angle equal to 180°
So,
a + 2x + 3x = 180°
40° + 5x = 180°
Subtract 40 from both side
40° - 40° + 5x = 180° - 40°
5x = 140°
Divide by 5 from both side
5x/5 = 140°/5
x = 28°
Thus, The value of x is 28°
FOR VERIFICATION ONLY:
a + 2x + 3x = 180°
40 + 2(28) + 3(28) = 180°
40° + 56° + 84° = 180°
180° = 180°
Hence, L.H.S = R.H.S
