Find x in the figure.

Question

one angle of the triangle is 35º, another angle is 40º. what is the third angle, x?

Answer 1

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.
