Answer:
3. x = 31 y = 139
4. x = 150 y = 145
5. x = 54
6. w = 50 x = 40 y = 85 z = 110
Explanation:
3. You can find y by doing 180 - 41. This is because straight lines are 180 degrees.
Then add all 3 angles up and subtract them from 360 to get x as 31.
4. You can find x by doing 180 - 30.
Then add all 3 angles up and subtract them from 360 to get y as 145.
5. Just divide 108 by 2, because the angle is split in half.
6. You can find angle y by going 125 - 40. We can do this by assuming the two angled across from each other are equal.
Add the 2 angles in the triangle on the left to get w.
w + x is a 90 degree angle so do 90 - w to get x
Then to get z add angle y + x + 125 then subtract that answer from 360
