Answer:

Step-by-step explanation:
First, we calculate the unknown angle of the left triangle and right triangle:
Unknown angle for left triangle⬆️

Unknown angle for right triangle⬆️
Now we've calculated the two angles for the small triangle in the middle. So, we just have to calculate the top angle of the middle triangle:

The angle 65° and angle of x are vertical angle.(both are equal)
So... <u>x= 65°</u>

Step-by-step explanation:
True? I dont know what you're trying to ask. if you're asking whether or not it's true, it is.
If it goes from a higher number to a lower number it is a decrease.
(15,295 - 9182) / 15295....x 100
6113 / 15295 = 0.399....x 100 = 39.9% decrease
