(4,1) there's the answer for you
All angles=40
therefore, internal angle= 140 degree
therefore, it has 5 sides
Answer:
Width = Length + 11
Perimeter:
(2 × Width) + (2 × Length) = 54 Feet
Substitute Width = Length + 11,
(2)(Length + 11) + (2 × Length) = 54
Length + 11 + Length = 54 ÷ 2
2Length + 11 = 27
2Legth = 27 - 11 = 16
Length = 16 ÷ 2 = 8
Width = 8 + 11 = 19
Answer:
Step-by-step explanation:
<u>As per diagram we have:</u>
<u>As per 30° right triangle property:</u>
- CD = √3×CB/2 = 3√3 ≈ 5.2 cm
- and
- AC = 2CD = 2×5.2 = 10.4 cm
<u>Area of triangle:</u>
- A = 1/2bh
- A = 1/2CB*AC
- A = 1/2*5.2*10.4 ≈ 27 cm²
