1. Look at the figure aboveWhat is the value of X?
Materi : Sudut
x = 180° - (55° + (180° - 83°))
x = 180° - (55° + 97°)
x = 180° - 152°
x = 28°
2. In the figure, ABCD is a parallelogram, CDF is a right-angled triangle, and CGF and DEF are straight lines. If the area of ACDF is 60 cm and 2CG = GF, find the area of the parallelogram ABCD.
Penjelasan dengan langkah-langkah:
2CG = CF
Area of ABCD = CD • CG
Area of CDF = (CD • CF)/2 = 60 cm²
Area of CDF = (CD • 2CG)/2 = 60 cm²
Area of CDF = CD • CG = 60 cm² = Area of ABCD.
So, the area of ABCD is 60 cm²
3. What is the value of the angle marked with x in the following parallelogram? jawab yang bener pls
kakak jawab pakai logika saja ya dek,,logika nya ada di gambar
nah jadi ½ lingkaran itu kan 180°,,jika di setengah lingkaran ada dua sudut dan sudut pertama sudah diketahui 113°,maka sudut yang satu nya lagi 180° - 113=67°
jadix=67°

7. 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
8. what is the value of x?
Jawaban:
x = 4
Penjelasan dengan langkah-langkah:
[tex] \frac{ {2}^{x + 2} + {2}^{x + 4} + {?}^{x + 6} }{128} = \frac{21}{2} [/tex]
[tex] {2}^{x + 2} + {2}^{x + 4} + {2}^{x + 6} = \frac{21}{2} \times 128[/tex]
[tex] {2}^{x + 2} + {2}^{x + 4} + {2}^{x + 6} = 1344[/tex]
[tex](1 + {2}^{2} + {2}^{4} ){2}^{x + 2} = 1344[/tex]
[tex](1 + 4 + 16) {2}^{x + 2} = 1344[/tex]
[tex]21 \times {2}^{ x + 2} = 1344[/tex]
[tex] {2}^{x + 2} = \frac{1344}{21} [/tex]
[tex] {2}^{x + 2} = 64[/tex]
[tex] {2}^{x + 2} = {2}^{6} [/tex]
[tex]x + 2 = 6[/tex]
[tex]x = 6 - 2[/tex]
[tex]x = 4[/tex]
jadi, nilai x adalah 4

20. · The coordinates of the parallelogram ABCD are: A = (5,2), B = (2, 4), C = (6, 7) and D= (9,5). What is the length of the shorter diagonal of parallelogram ABCD?
Jawab:
[tex]\sqrt{26}[/tex]
Penjelasan dengan langkah-langkah:
Rumus jarak titik P(a, b) dengan titik Q(c, d) adalah [tex]|PQ|=\sqrt{(c-a)^2+(d-b)^2[/tex]
diagonal dari jajar genjang tersebut adalah AC dan BD. dengan rumus jarak dua titik didapat
[tex]|AC|=\sqrt{(6-5)^2+(7-2)^2}=\sqrt{1+25}=\sqrt{26}\\|BD|=\sqrt{(9-2)^2+(5-4)^2}=\sqrt{49+1}=\sqrt{50}\\\\[/tex]
karena yang diminta panjang diagonal terpendek, maka panjangnya adalah [tex]\sqrt{26}[/tex]
