Question

find the value of y in following triangle ​

Answer 1

Answer:

30 degree is the answer

Answer 2

Answer:

The value of y= 30°

Step-by-step explanation:

It's an remote interior angle theorem.

• 75°+ the third angle = 180°

•180-75= 105°

Therefore the third angle is 105°

Now,

The sum of three sides of a triangle= 180°

•45+105+ y = 180°

•y=150=180

•y=180-150= 30°

Therefore, y=30°
