x = 115°

Step-by-step explanation:

We know that a triangle has 180° in total when you add up all the interior angles. So in order to find the value of x°, we need to find the missing angle in the triangle itself:

180°-(75°+40°)

= 180° - 115°

= 65°

To find x°, we know that the 65° angle + x° is equal to 180° because it's a supplementary angle. So:

x° + 65° = 180°

x° = 115°
