In triangle XYZ, the measure of angle Y is twice the measure of angle X, and the measure of angle Z is three times the measure of angle X, what is the measure of angle Y ?
since
X+Y+Z=180,
X+2X+3X=180
X=30
Y=60
Sir i wnat maths

To find the measure of angle Y in triangle XYZ, we need to know the measure of angle X. However, the information you have provided only gives a relationship between the measures of the three angles.
Let's assume the measure of angle X is represented by the variable 'x'. According to the given information, the measure of angle Y is twice the measure of angle X, so angle Y can be represented as 2x. Similarly, the measure of angle Z is three times the measure of angle X, so angle Z can be represented as 3x.
Now, we know that the sum of all angles in a triangle is 180 degrees. In triangle XYZ, the measure of angle X + measure of angle Y + measure of angle Z = 180 degrees.
We can substitute the values we found earlier into this equation and solve for x:
x + 2x + 3x = 180
Combining like terms, we get:
6x = 180
Dividing both sides by 6, we find:
x = 30
Now that we have the value of x, we can find the measure of angle Y by substituting x = 30 into our equation for angle Y:
Y = 2x = 2(30) = 60
Therefore, the measure of angle Y in triangle XYZ is 60 degrees.
