Adjacent means next to each other and vertical literally means vertical, or linearly across from each other. Since angle x is next to the 35 degree angle, they are adjacent angles.
To find x, we know that the little box on the bottom left corner means a right angle, or 90 degree angle. Since we know the other angle's value, we do 90 - 35 = 55 degrees.
1 yard = 3 feet
40 ÷ 3 = 13.33...
Round and it is near 13 yards
2(Length+width)
2(8+4)=
2(12)=24
Answer:24
The answer will be 207 with a remainder of 3. I attached my paper work for you to see the actual steps.
