The values of three angles at a point are 3y - 45o, y + 25o and yo . Find the value of y.

The values of three angles at a point are 3y - 45^o, y + 25^o and y^o . Find the value of y.

Answer Details

When three angles at a point are added together, they sum up to 360 degrees. Therefore, we have: (3y - 45) + (y + 25) + y = 360 Simplifying the equation, we get: 5y - 20 = 360 Adding 20 to both sides, we get: 5y = 380 Dividing both sides by 5, we get: y = 76 Hence, the value of y is 76 degrees, and the correct option is (d) 76^o.
