vesna_86 [32]

Answer:12 m

Step-by-step explanation:

Given

Width of garden W=8\ m

Total fencing T=40\ m

If Lulu has enough fencing to go around her rectangular garden then , it should be equal to perimeter of garden

Suppose L is the length of garden

Therefore perimeter is P=2(L+W)

2(L+W)=40

L+W=20

L=20-8=12\ m

thus length of fencing is 12\ m

Find all the missing elements:
Evgesh-ka [11]

Answer:

a=10.8; c=4.3

Step-by-step explanation:

The sum of all the angles in a triangle is 180 degrees.

Two of the angles are given as 40 deg and 120 deg.

Subtract the measures of both from the sum to get the last angle:

180-40-120=20; ∠C=20°

Using Law of Sines: \frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}

\frac{a}{sin120}=\frac{8}{sin40}; a=\frac{8*sin120}{sin40}; a=10.77837084

\frac{c}{sin20}=\frac{8}{sin40}; a=\frac{8*sin20}{sin40}; c=4.25671109
