Question

The value of y in the given figure is
(a) 60° (b) 45° (c) 320 (d) 220​

Answer 1

y = 22 degree.

Step-by-step explanation:

Any straight line has an angle of 180degree.

Therefore, 2y + 74 + 62 = 180

2y + 136 = 180

2y = 180-136. (taking +136 to R.H.S)

2y = 44

y = 44÷2. (taking ×2 to R.H.S)

y = 22

Answer 2

As per the data given in the question,

We have to determine the value of "y".

As we know that,

Sum of all angles formed on a single line will be 180 degree.

So, from the question,

We can say that,

$2y + 74^0+62^0=180^0$

So, we will get it as,

$2y + 74^0+62^0=180^0\\=>2y = 180^0-74^0-62^0\\=>2y = 44^0\\=>y=\frac{44^0}{2} = 22^0$

Hence, value of missing angle will be 44 degree.

So, the value of y will be 22 degree.
