Answer:
y = 22.5
Step-by-step explanation:
Here, the 4 angles shown are all exterior angles of the polygon.
The sum of the exterior angles of a polygon is ALWAYS 360°
<em>So we add up the 4 angles (given in terms of y) and sum it to 360 and solve for y:</em>

y = 22.5
Answer:
0
Step-by-step explanation:
78/17 gives 4.588
In rounding up numbers, 1 to 4 is rounded up to zero, while numbers 5 to 9 will be rounded up to 1.
In the question above, we are asked to round up to the nearest 10. And then 78/17 gives 4.588
This number is between 0 and 10.
The whole number there is 4. Therefore, 4 will be rounded up to Zero.
If the question and us to round up to the nearest whole number, as we have 4.588
The number before the whole number 4 is 5 (the tenth digit), and then 5 will be rounded up to 1. That 1 will hence be added to 4.
4+1= 5. To nearest whole number, it is 5 but to nearest ten, it is 0
Ok, we know that there are 270 degrees in a triangle, so just add 49+57, the you'll get 106, 270-106=164. ANSWER: 164
I think this is True. Because Perpendiculer Lines Rely On Right Angles. :)
