Answer:
Step-by-step explanation:
The sum of the angles in a triangle = 180°
∠TUV + ∠TVU + ∠UVT = 180°
78° + 54° + ∠UVT = 180°
∠UVT = 48°
=> alternate angles (property of a parallel line), as SR is parallel to TU.
∠UVT = ∠SRV = 48°
Let W and L be width and length of the rectangular pen respectively.
Therefore,
Circumference, C = 2W+2L= 130 yd
Area, A = LW = 1050 yd^2=> L = 1050/W
Using the circumference expression and substituting for L;
130 = 2W + 2(1050/W) = 2W+2100/W
130*W = 2W*W + 2100
130W = 2W^2 +2100
2W^2-130W+2100 = 0
Solving for W;
W= [-(-130)+/- Sqrt ((-130)^2-4(2)(2100)]/2*2 = 32.5+/- 2.5
W = 30 or 35 yd
When W = 30, L = 1050/30 = 35
When W = 35, L = 1050/35 = 30
Therefore, W = 30 yd and L = 35 yd.
