Question

What is the value of y ?​

Answer 1

Answer:

Here value of y will be 54⁰

Step-by-step explanation:

here 3x+72⁰=180⁰

= x=108⁰/3=36⁰

also x +90⁰+y=180(linear pair)

hence ,y=180⁰-90-36⁰

y=54⁰

Answer 2

$\huge\mathcal\pink{Answer}$

Let's find the value of x first

=> 3x + 72° = 180°
linear pair

=> 3x = 108
=> x =$\frac{108}{3}$
= x = 36°

Now we also know that ,

= x + 90 + y = 180
linear pair

= 36 + 90 + y = 180
= y = 180 - 36 - 90
= y = 54°
