1. In the figure below, the two triangles are similar. What is the value of x? *
5 : 6 = 11 : x
5x = 66
x = 66 : 5
x = 13,2
2. A figure is made up of a rectangle and a semicircle as shown in the diagram below. what is the area of the figure?
Jawab:
Area itu bahasa inggris dari Luas, maka
Area of square = S x S
= 7 x 7
= 49 cm²
Radius = Diameter / 2
= 7 / 2
= 3.5 cm
Area of [tex]\frac{1}{2}[/tex] circle = [tex]\frac{1}{2}[/tex] x [tex]\pi[/tex] x r²
= [tex]\frac{1}{2}[/tex] x [tex]\frac{22}{7}[/tex] x 3.5²
= 19.25 cm²
Are of the figure = 49 + 19.25 = 68.25 cm²
Penjelasan:
phi [tex](\pi )[/tex] untuk [tex]\frac{22}{7}[/tex] digunakan apabila jari-jari/radius berkelipatan 7, sedangkan
phi untuk 3.14 digunakan apabila jari-jari/radius tidak berkelipatan 7
3. in the figure below,the value of x is.... cm
6 / 18 = x / x + 16
18x = 6x + 96
18x - 6x = 96
12x = 96
x = 96/12
x = 8
4. 5. look at the figure below! (Perhatikan gambar di bawah ini!)In the above figure, the the measure of LA2 = 75º. Find the measuring of:tenokar pongukurana. ZB3b. LA1c. LB4
Penjelasan dengan langkah-langkah:
∠A2 = 75°
a. ∠B3 = 180° - ∠A2
= 180° - 75°
= 105°
.
.
b. ∠A1 = ∠B3 = 105°
.
.
c. ∠B4 = ∠A2 = 75°
a.
< B₂ = < A₂ = 75° (karena sehadap)
< B₂ + < B₃ = 180° (berpelurus)
< B₃ = 180° - < B₂
< B₃ = 180° - 75°
< B₃ = 105°
b.
< A₁ + < A₂ = 180° (berpelurus)
< A₁ = 180° - < A₂
< A₁ = 180° - 75°
< A₁ = 105°
c.
< B₄ = < A₂ (karena berseberangan luar)
< B₄ = 75°

8. Look at the picture below. If the side of a small square is 2 cm, then what is the area of the figure?
2² x { L (1+2) + L (3+4) + L5 + L6 + L7
= 4 x { 3 + 2 + 3 + 4 + 6 }
= 4 x { 18 }
= 72 cm² ✔️
The area of the figure is 72 cm².

9. what is the area of the figure?
L = ((1,5 + 2,5 + 1,5) × 5) - 2 × (2,5 × 3,5 ÷ 2)
L = (5,5 × 5) - 8,75
L = 27,5 - 8,75
L = 18,75cm²

11. Find the value of x in the figure below.
Jawaban:
2x + 5x + 3x + 90° = 360°
10x + 90° = 360°
10x = 360° - 90°
10x = 270°
x = 270°/10
x = 27°

15. Find the value of x in the figure below.
X + 12° + (180° - 43°) = 180°
x + 12° + 137° = 180°
x + 149° = 180°
x = 180° - 149°
X = 31°

16. I try to figure in the answer of what the function of the organization is Soal eror?? A. I B. Figure in C. What D. Is
Jawaban:
The error:
B. Figure in
Pembetulan:
Bahasa Inggris dari mencari tahu adalah figure out, bukan figure in (Phrasal Verb).
Penjelasan:
I try to figure in the answer of what the function of the organization is.
Pembetulan:
I try to figure out the answer of what the function of the organization is.
Phrasal Verb yang tepat untuk kalimat di atas adalah figure out bukan figure in. Karena yang bermakna mencari tahu adalah figure out, bukan figure ini. Kalimat di atas juga bukanlah kalimat tanya, meskipun terdapat kata tanya "what" dan "is". Maka dari itu, peletakan kata "is" di akhir kalimat, sebagai tanda yang menunjukkan bahwa kalimat tersebut adalah kalimat positif atau berbentuk pernyataan, bukan pertanyaan.

17. The figure is made up of three identical semicircles in a largesemicircle. The radius of the large semicircle is 21 cm. What isthe perimeter of the shaded figure?
Jawaban:
22/7×21×21=1386
maaf ya klau slh
18. Find the area of the shaded part in the figure below
4. Area = 49.2075 m²
5. Area = 63.25 m²
Penjelasan/Explanation
Number 4
The area of that figure equals to the area of the square minus the area of the semicircle.
The length of each side: s = 9 mRadius of semicircle: r = ½sA = s² – ½πr²
⇔ A = s² – ½π(½s)²
⇔ A = s² – ½(¼πs²)
⇔ A = s² – (1/8)πs²
⇔ A = s²[1 – (1/8)π]
⇔ A = 9²[1 – (1/8)×3.14]
⇔ A = 81(1 – 0.3925)
⇔ A = 81(0.6075)
⇔ A = 49.2075 m²
Number 5
The area of that figure equals to the sum of the area of the right-angled triangle and the area of the semicircle.
Base of triangle: b = 8 mHeight of triangle: h = 6 mRadius of semicircle: r = (½×10) m = 5 mA = ½bh + ½πr²
⇔ A = ½(bh + πr²)
⇔ A = ½(8×6 + 3.14×5²)
⇔ A = ½(48 + 3.14×25)
⇔ A = ½(48 + 78.5)
⇔ A = ½(126.5)
⇔ A = 63.25 m²
KESIMPULAN/CONLUSION4. Area = 49.2075 m²
5. Area = 63.25 m²
