1. in the diagram , ABC is a straight line.find the value of x
Karena garis ac melewati dua garis sejajar jadi
Sudut x = sudut bcd
Sudut bcd =(180-30)/2
= 150/2
= 75°
Jadi besar sudut x adalah 75°Hai Sobat Brainly!
Pertanyaanmu :
In the diagram, ABC is a straight line. Find the value of x!
Jawabanku :
Diketahui
Sudut CBD = 30°
Δ CBD = segitiga sama kaki, yang dimana dudt yang berada sebagai kaki sama besarnya,
maka Sudut BCD = Sudut BDC
Dan disini x merupakan sudut yang sama besarnya dengan BCD dikarenakan sudutnya sehadap.
Jika y merupakan besar sudut BCD dan BDC, maka
2y + 30° = 180°
2y = 180° - 30°
2y = 150°
y = 75°
y = x
x = 75°
So, the value of x is 75°

3. find the value of x
Jawaban:
10
Penjelasan dengan langkah-langkah:
11x + 7 + 6x + 3 = 180
17x + 10 = 180
17x = 180 - 10
17x = 170
x = 170 : 17
x = 10
Jawaban:
10°
Penjelasan dengan langkah-langkah:
11x + 7 + 6x + 3 = 180
17x + 10 = 180
17x = 180 - 10
17x = 170

4. Find The value of x 77.5% of x =17
Jawaban:
77,5/100 x = 17
x= 17× 100/77,5
x= 68/3,1
5. find the value of x and y!
Jawaban:
X: 26
y:91
Penjelasan dengan langkah-langkah:
hope this helps
Answer:
x = 26⁰, y = 91⁰
Description:
x + y + 63⁰ = 180⁰
x + 91⁰ + 63⁰ = 180⁰
x + 154⁰ = 180⁰
x = 180⁰ - 154⁰
x = 26⁰
26⁰ + y + 63⁰ = 180⁰
89⁰ + y = 180⁰
y = 180⁰ - 89⁰
y = 91⁰
6. Find the value of X
Jawab:
47
Penjelasan dengan langkah-langkah:
1.
Garis lurus:180
Sudut sebelah 117:
180-117:
:63
karena bersebrangan maka :
X:180-(30+40+63)
x:180-133
x:47
[tex]\left[\begin{array}{c}KHAZZAMY\\MATH\\BRAINLY\end{array}\right][/tex]
Jawab:47°
Penjelasan dengan langkah-langkah:How to find the value of X:
Eng:
Total degrees of circle: 360°
If we look at the total with the radius under it is half the circle or 180°
And those that are not marked with X are equal to 63°
(because 117° - 180° = 63°)
So.. to find the value of X is:
63° + 30° + 40 = 133°
180° + 133° = 47°
Indo:
Derajat total lingkaran: 360°
Jika kita melihat total dengan juring di bawahnya adalah setengah lingkaran atau 180°
Dan yang tidak bertanda X sama dengan 63° (karena 117° - 180° = 63°)
Jadi .. untuk mencari nilai X adalah:
63° + 30° + 40° = 133°
180° + 133° = 47°
Semoga membantu;)

7. Find the value of 21 x 17
Jawaban:
357
Penjelasan dengan langkah-langkah:
karna itu adalah 21x17
jadi 21x17=357
8. 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°
Maaf klo ada yg salah
9. find the value of 'x' 9x=27
9x = 27
divide the both sides by 9
9x ÷ 9 = 27 ÷ 9
x = 3
so , the value of x is 3
9x=27
×=27/9
×=3
the value of x is 3

Penjelasan dengan langkah-langkah:
12. find the value of x
1) 3x + 6x membentuk sudut siku siku maka:
3x + 6x = 90°
9x = 90°
x = 90°/9
x = 10°
2) 2a + 3a + 20 = 180°
5a + 20 = 180°
5a = 180 - 20
5a = 160
a = 160/5
a = 32
3) z = 120°
y = x = 180-120
y = x = 60°
4) 4/6 = 6/a
a = 6×6/4
a = 9 cm

13. 13. In Diagram 3, the FG is parallel to the line Hl. 3x Find the value of x. G 2x
Based on the information provided, it is not possible to determine the value of x without additional information. The diagram and the statement "FG is parallel to the line Hl" do not provide enough information to solve for x. To find the value of x, we would need to know more about the size of the angles and the lengths of the lines in the diagram.

15. Find the Value of X (Photo Included)
Jawaban:
sudut pusat = 2 kali sudut keliling
sudut pusat = 2 × 70°
sudut pusat = 140°
5x - 10 = 140
5x = 150
x = 30°
Jawaban:
x = 30°
Penjelasan dengan langkah-langkah:
DPE = sudut pusat
DFE = sudut keliling
sudut pusat = 2 × sudut keliling
DPE. = 2 × DFE
5x - 10°. = 2 × 70°
5x - 10°. = 140°
5x. = 150°
x. = 150° ÷ 5
x. = 30°

17. find the value of x + y !
Jawab:
Penjelasan dengan langkah-langkah:
2x + y = 180 (i)
(x-19) + y + 90 = 180 (ii)
------------------------------
2x + y = 180
(x-19) + y = 90
---------------------- (eliminasi)
2x - (x-19) = 90
x +19 = 90
x = 90-19 = 71
---------------------
2x + y = 180
2(71) + y = 180
142 + y = 180
y = 180-142 = 38
x + y = 38 + 71 = 109
18. find the value of x
Jawab:
x = 11
Penjelasan dengan langkah-langkah:
9x + 6 + 7x - 4 + 7x + 5 + 5x - 4 + 4x + 5 = 360
32x + 8 = 360
32x = 360 - 8
32x = 352
x = 352 : 32
x = 11
Jawaban:
11
Penjelasandenganlangkah-langkah:
9x + 6 + 7x - 4 + 7x + 5 + 5x - 4 + 4x + 5 = 360 (<'s at a point)
9x + 7x + 7x + 5x + 4x = 360 - 6 + 4 - 5 + 4 - 5
32x = 352
x = 352/32
x = 11
⁂ x = 11
so, the value of the x is 11.
Semoga membantu. maaf kalo salah,

19. Find the value of x!
Jawaban:
angle a = 50°
angle b = 70 °
angle c=x
angle a + angle b + angle c = 180°
50°+70°+x=180°
120°+x=180°
x=180°-120°
x=60°
Hence, option (a) is the right answer.
HOPE IT HELPS YOU.....
