You first add all the angles together.
25 + 65 + 90 = 180°
The total angle measurement of a triangle is 180°. Therefore, it is possible to only make one triangle.
-3x + 4 = -17
-3x = -21
-x = -7
x = 7
The answer is 7

Answer:
I would use similar triangles
Step-by-step explanation:
There is no angle (apart from the right angle) given in the problem. so in order to find the side "x", in one step calculation, I would use similar triangles and the equation that comes from the proportion among the similar sides:
