Answer: x = 35
Step-by-step explanation:
145 + 35 = 180°, and if <JKL are straight angles, they must be 190 degrees in total. Therefore X must equal to 35°.
By solving a simple equation, we will see x = 35°.
In the image we can see that the 145° angle and x should add up to a 180° angle, so we can write the equation:
145° + x = 180°
Now we can solve that for x, by subtracting 145° on both sides, so we get:
x = 180° - 145° = 35°
The solution is x = 35°
