Question

in the given figure x=4y and z=5y then the value of y is​

Answer 1

Step-by-step explanation:

Given, x = 4y and z = 5y

To show : y

Solution : x + y + z = 180°

=> 4y + y + 5y = 180°

=> 10y = 180°

=> y = 180/10

=> y = 18°

Answer 2

SOLUTION

GIVEN

In the given figure x = 4y and z = 5y

TO DETERMINE

The value of y

EVALUATION

Here it is given that x = 4y and z = 5y

From the given figure we observe that

AOB is a straight line and sum of all the angles in a straight line is 180°

So we have

x + y + z = 180°

⇒ 4y + y + 5y = 180°

⇒ 10y = 180°

⇒ y = 18°

FINAL ANSWER

Hence the required value of y = 18°
