To find the missing angle, use the fact that the sum of the angles in a triangle is always 180 degrees.
So, the sum of the given angles is 35 + 40 + y = 75 + y.
This sum added to the missing angle of X should be equal to 180 degrees:
75 + y + X = 180
Substitute the given values:
75 + y + X = 180
Combine like terms:
y + X = 105
Since we know that y is unknown, the angles 35, 40, and X sum to 105 degrees. Therefore:
35 + 40 + X = 105
Combine like terms:
75 + X = 105
Subtract 75 from both sides:
X = 30 degrees
Therefore, the missing angle X is 30 degrees.
Find the X
One angle is 35 one is 40 and one is y

That is incorrect
My apologies for the mistake.
Let's correct the calculation:
Given angles: 35, 40, and y
Sum of angles in a triangle = 180 degrees
35 + 40 + y + X = 180
75 + y + X = 180
y + X = 105
We know that y is unknown, so the angles 35, 40, and X sum to 105 degrees:
35 + 40 + X = 105
75 + X = 105
X = 105 - 75
X = 30 degrees
Therefore, the missing angle X is indeed 30 degrees. Thank you for pointing out the mistake.
