Find x in the figure.
one angle of the triangle is 35º, another angle is 40º. what is the third angle, x?
To find the third angle of the triangle, we can subtract the sum of the given angles from 180º, because the sum of the angles in a triangle is always 180º.
So, the sum of the given angles is 35º + 40º = 75º.
Now, let's subtract the sum of the given angles from 180º to find the third angle:
180º - 75º = 105º
Therefore, the third angle, x, is 105º.
