Two angles are supplementary when they <span>add up to 180 degrees.
x = </span><span>smaller angle
</span>2x+3 =<span> larger angle
x + 2x + 3 = 180
3x = 180 - 3
3x = 177
x = 177/3
x = 59</span>° ← smaller angle
2x + 3 = 2*59 + 3 = 121° ← larger angle

Step-by-step explanation:
Answer:
Area = 34. 81 yd^2
Perimeter = 86.6 feets
Step-by-step explanation:
Given the following :
Shape of Mrs. Johnson's plot = square
All sides of a square are of equal length
Measure of each side = 5.9 yd
A.) Area of plot
Area of plot = Area of a square
Area of a square(A) = a^2
Where a = side length
A = 5.9^2
A = 34.81 yd^2
B) Perimeter of Basil plot = Perimeter of a square
Converting yard to feet
1 yard = 3feets
Therefore,
5.9 yards = (3 * 5.9) = 17.7 feets
Fence is 2ft from the garden on each side,
Length of fence on each side = (2 + 17.7 + 2) Feets = 21.7 Feets
Perimeter of a square (P) = 4a
Where a = side length
P = 4 × 21.7
P = 86.6 feets
