Question

Find the X

One angle is 35 one is 40 and one is y

Answer 1

That is incorrect

Answer 2

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.

Answer 3

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.
