Answer:
Perimeter of rectangle added 2 to length:
perimeter of rectangle= length + width + length + width
P = ( l + 2 ) + w + ( l + 2 ) + w
P = 2 ( l + 2 ) + 2 w
P = 4 + 2 l + 2 w
Perimeter of rectangle added 2 to width:
P = l + w + l + w
p = l + ( w + 2) + l + ( w + 2)
p = 2 l + 2 ( w + 2)
p = 2 l + 2 w + 4
The Answer to this solution is -14r
Answer: 60° angle
Step-by-step explanation: AGD is a 90° angle, therefore, subtracting 30 from the 90 degrees gives you 60. As x is vertical to the 60 degree angle and verticals have the same degree measurement, x=60°.
