If one corner of the triangle is 40 dgrees, and another is 35 degrees what is y?

1 answer

To find the measure of the third angle of the triangle, we need to subtract the sum of the other two angles from 180 degrees (since the sum of the angles in a triangle is always 180 degrees).

Let's call the measure of the third angle y.

The sum of the first two angles is 40 + 35 = 75 degrees.

Now, subtracting this sum from 180, we have:

180 - 75 = 105 degrees

Therefore, the measure of the third angle is y = 105 degrees.
