Question

In the given figure find the value of y​

Answer 1

Answer:

15

Step-by-step explanation:

4y+5y+3y=180°

12y=180°

y=180/12=15

y=15

Answer 2

Given: The figure is given.

To find: The value of $y$

Solution:

In the given figure,

∠COE  $=4y$

∠AOF $=5y$

∠DOB $=3y$

To find the value of $y$ we need to apply the corollary that is,

The sum of all the angles around a centre is equal to $360^o$

Applying the above corollary,

∠COE + ∠AOF + ∠DOB $=360^o$

⇒ $5y+4y+3y=360$

⇒ $12y=360$

⇒$y=\frac{360}{12}$

⇒ $y = 30$

Final answer:

Hence, the value of y is $30$
