Answer:
x = 85
Step-by-step explanation:
There are two triangles. For the purpose of communication, I label them as right triangle and acute triangle.
All triangles' interior angles must add to 180°.
Since we already have two of the three angles in the acute triangle, we can find the third angle, which I label as "y":
180° = 25° + 60° + y
180° = 85° + y
180° - 85° = 85° - 85° + y
y = 95°
Supplementary angles are angles that add to 180°. This is true of any straight lines.
In this question, the angles x and y are supplementary because they make up a straight line.
x + y = 180°
x + 95° = 180°
x = 85°
Without all these steps, we can also figure out that x = 85 by adding 60° and 25° because the sum of a triangles' two interior angles are equivalent to the supplementary of the third angle.
