3. (b) The area of triangle ABC is twice the area of triangle DBE.
Penjelasan dengan langkah-langkah:
[tex]area \: triangle \: abc = \frac{1}{2} \times base \times height \\ = \frac{1}{2} \times 8 \times 14 = 56 \: {cm}^{2} \\ area \: triangle \: abc \: = 2 \times area \: triangle \: dbe \\ 56 = 2 \times area \: triangle \: dbe \\ area \: triangle \: dbe \: = \frac{56}{2} = 28 \: {cm}^{2} [/tex]
4. Perimeter of a triangle is 217 cm.the ratio of the triangle sides are 5:9:17 find the length of each side of the triangle
Answer :
Known Values :
Perimeter (P) = 217 cm
Ratio of the sides = 5 : 9 : 17
First, find the value of each "1x" in the ratio ;
=> 217 cm : (5 + 9 + 17)
=> 217 cm : 31
=> 7 cm
Now, we can search each length of each side of the triangle according to the value of each "1x" we searched before.
"A" side :
=> 5 × 7 cm
=> 35 cm
"B" side :
=> 9 × 7 cm
=> 63cm
"C" side :
=> 12 × 7 cm
=> 84cm
So, we found the length for each side in the triangle are 35 cm, 63 cm, and 84 cm.
5. If the size of the angles of triangle are 3x°,4x°,5x°.the smallest angle of the triangle is
Jawaban Master Teacher
12x = 180°
x = 15°
smallest angle
3x = 45°6. The area of a triangle is 528cm2. the length of its base is 33cm. calculate the perpendicular height of the triangle.
Diketahui:
Luas segitiga = 528 cm²
Panjang alas = 33 cm
Tinggi = ?
[tex]luas \: = 528 \\ \frac{1}{2} \times a \times t = 528 \\ \frac{1}{2} \times 33 \times t = 528 \\ t = \frac{528 \times 2}{33} \\ t = 32[/tex]
Jadi, tinggi segitiga adalah 32 cm.
Jawab:
32
Penjelasan dengan langkah-langkah:
L=528
a= 33
L= a*t/2
528= 33*t/2
1056=33t
t= 1056/33
t=32

8. There are types of triangles based on the side.....except: A. Obtuse Triangle B. Equilateral Triangle C. Isosceles Triangle D. Scalene Triangledibantu iya
Jawaban:
A. Obtuse Triangle (Segitiga Tumpul)
Penjelasan:
A. Obtuse Triangle (Segitiga Tumpul)
B. Equilateral Triangle (Segitiga Sama Sisi)
C. Isosceles Triangle (Segitiga Sama Kaki)
D. Scalene Triangle (Segitiga Sembarang)
Jawabannya yg A karena Segitiga Tumpul termasuk dalam segitiga yg ditinjau dari Sudutnya, sedangkan yg B, C, dan D itu termasuk dalam segitiga
yg ditinjau dari PanjangSisi-sisinya.
Jawaban:
A. Obtuse triangles
Langkah langkah :
Pertanyaan :
There are types of triangles based on the side except :
Artinya :
Ada jenis jenis segitiga berdasarkan sisinya kecuali :
Pilihan jawaban :
A. Obtuse triangle = segitiga
tumpul
B. Equilateral triangle = segitiga
sama sisi
C. Isosceles triangle = segitiga
sama kaki
D. Scalene triangle = segitiga
sembarang
Penjelasan :
Menurut jenis sisinya, segitiga dibagi menjadi 3 jenis
1. Segitiga sama sisi = ketiga sisi
nya sama panjang dan ketiga
sudutnya sama besar
2. Segitiga sama kaki = Hanya
memiliki 2 sisi sama panjang
dan 2 sudut sama besar.
3. Segitiga sembarang =
segitiga yang masing masing
sisinya tidak sama panjang
dan masing masing sudutnya
tidak sama besar.
Sedangkan segitiga sembarang (scalene triangle) merupakan segitiga berdasarkan jenis sudutnya.
Jadi, jawaban yang tepat untuk pertanyaan diatas adalah
= A. Obtuse triangle

12. 18. If the size of the angles of triangle are 3x°,4x°and 5x°. The biggest angle of triangle is ...
sudut segitiga = 180°
3x° + 4x° + 5x° = 180°
12x = 180
x = 180/12
x = 15
sudut terbesar = 5x = 5 × 15 = 75°

16. The base of a triangle is longer than twice its corresponding height by 1 cm. The area of the triangle is 105 cm?. Find the height of the triangle!butuh cepat
Jawaban:
52,5
Penjelasan dengan langkah-langkah:
105:2 sorry if wrong
Jawab:
The height of the triangle is 10 cm.
Penjelasan dengan langkah-langkah:
If the area, base and height of that triangle are notated by A, b and h, then it is known that:
A = (1/2)bh
b = 2h+1
So:
A = (1/2) × (2h+1) × h
A = (1/2) × (2h²+h)
2A = 2h²+h
2×105 = 2h²+h
210 = 2h²+h
2h²+h-210 = 0
(2h+21)(h−10)=0
2h+21=0 or h−10=0
h = -21/2 or h = 10
The positive solution is h = 10, so the height of the triangle is 10 cm.
Proof:
If the height is 10 cm, then the base equals to 21 cm (2×10 + 1 = 21).
The area of the triangle:
A = (1/2)bh = (1/2)(21)(10) = (1/2)(210) = 105 cm². (correct!)

18. The lenght of the legs of an isosceles triangle is 4 meters more than its base. If the perimeter of the triangle is 44 meter. Determine the lenghts of the sides of the triangle!bantuin plisss
Jawaban:
4meter x 44meter = 176 meter
Penjelasan dengan langkah-langkah:
Sisi x sisi x sisi
Isosceles triangle = segitiga sama kaki.parimeter = keliling
k= 44m..
kaki nya = 4cm lebih dari sisi bawah.
caranya
K = a + b + c
44 = (4+x) + (4+x) + x
44 = 8 + 3x
44-8 = 3x
36 = 3x
x = 36/3
x = 12
berarti sisi nya =
kaki = 12+ 4 = 16m
sisi bawah = 12m
ini ya kak jawabannya ..

20. Find the area of triangle
First, find the area of the biggest triangle. With the given base and height, [tex] 18 + 8 = 26 [/tex] cm and [tex] 7 [/tex] cm, respectively, we get
[tex] \displaystyle \mathcal{A}_\text{biggest} = \frac{1}{2} \times 7 \times 26 = 91 [/tex]
and the smallest triangle, we have [tex] 8 [/tex] cm and [tex] 7 [/tex] cm, respectively, and yields
[tex] \displaystyle \mathcal{A}_{\text{smallest}} = \frac{1}{2} \times 8 \times 7 = 28 [/tex]
If we want to find the gray area, then we should subtract the biggest with the smallest one. And it gives us
[tex] \displaystyle \underset{\text{Gray}}{\mathcal{A}} = 91 - 28 = 63 [/tex]
