5. 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°

Kita translite ke Bahasa Indonesia dulu
Pada gambar, AB || CD.
(a) Daftar ke bawah
(1) dua pasang sudut yang bersesuaian sama besar,
(ii) dua pasang sudut yang sama besar,
(iii) dua pasang sudut dalam yang bersuplemen.
(b) Apakah BWQ = AXR? Jelaskan jawabanmu.
c) Apakah jumlah DYP dan CZR sama dengan 180? Jelaskan jawaban Anda
Garis dan SudutJawaban
A.
(i) 2 Pasang sudut yang bersesuaian sama besar adalah
< W = < X
< Y = < Z
(ii) 2 Pasang sudut yang sama besar
< W = < X
< Y = < Z
(iii) 2 Pasang sudut dalam yang tambahan
< YWX dan < ZXW
< WYZ dan < XZY
B. BWQ = AXR
Tidak sama karena < BWQ lebih landai dibandingkan dengan < AXR yang lebih lancip
C. DYP + CZR = 180⁰
Ya, karena < DYP dan < CZR saling berhadapan maka jumlah kedua sudut adalan 180⁰

7. the sum of three angles of triangle of 180 deg. the sum of two of the angles is equal to the third angle and the difference of the two angles is equal to 2/3 the third angles find the angles of this triangle?
suppose that :
x = first angle
y = second angle
z = third angle
The sum of three angles of triangle of 180°
So :
x + y + z = 180
The sum of two of the angles is equal to the third angle
So :
x + y = z
The difference of the two angles is equal to 2/3 the third angles
So :
x - y = (2/3) z
subtitute x + y = z
x + y + z = 180
z + z = 180
2z = 180
z = 180/2
z = 90
x + y = z
x + y = 90
x - y = (2/3) z
x - y = (2/3) (90)
x - y = 60 >>> x = 60 + y
subtitute x = 60 + y
x + y = 90
60 + y + y = 90
60 + 2y = 90
2y = 90 - 60
2y = 30
y = 30/2
y = 15
x = 60 + y
x = 60 + 15
x = 75
We got :
x = 75
y = 15
z = 90
So, the angles are 75°, 15°, and 90°
8. in an isosceles triangle,one angle is three times the size of the other two angles. Work out the size of each angle.
Jawab:
Penjelasan dengan langkah-langkah:
Penjelasan dengan langkah-langkah:
total angles in a triangle is 180.
one angle is three times the size of the other two angles.
so:
x + x + 3x = 180
5x = 180
x = 36 degrees (size of each base angles)
one angle is three times the size of the other two angles
first angle: 36
second angle: 36
third angle: 3 × 36 = 108
9. 3. In the diagram, the sizes of two angles are marked.a What other angles are 105°?b What other angles are 75°?
Jawab:
a) 105⁰ = q⁰, r⁰, u⁰
b) 75⁰ = p⁰, s⁰, t⁰
Penjelasan dengan langkah-langkah:
105⁰ opposite with q⁰ so it's equal
105⁰ have same direction with r⁰ so it's equal
r⁰ opposite with u⁰ so it's equal too
For 75⁰ the explanation it's the same
10. 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°11. If the angles of a triangle are inthe ratio 1:3:5, then how many degrees are in the measure of the smalest angle?
Jawab:
Penjelasan dengan langkah-langkah:
Jawaban:
angles ratio = 1 : 3 : 5
= x, 3x, 5x
smallest angle = x
total angles in triangle = 180⁰
x+3x+5x= 180
9x= 180
x= 20⁰---------

12. If the angles of a triangle are inthe ratio 1:3:5, then how many degrees are in the measure of the smalest angle?
Jawaban:
22.5 degrees
Penjelasan:
one triangle has total of 360 degrees
so :
one plus three plus five equals eight
small angle of triangle has a ratio 1 of 8 (1/8)
1/8 . 180 = 22.5 degrees
13. Apa terjemahan bahasa Indonesia dari: - Supplementary Angles - Complementary Angles - Corresponding Angles - Alternate interior Angles - Alternate exterior Angles - Opposite Angles
- Tambahan Angles

bahasa nya kenapa bahasa inggris kak
15. Apa yang dimaksud dengan: - Supplementary Angles - Complementary Angles - Corresponding Angles - Alternate interior Angles - Alternate exterior Angles - Opposite Angles
- sudut suplemen atau sudut yang berpelurus Sifat : Kalo dijumlahkan hasilnya 180 derajat - sudut komplemen atau berpenyiku Sifat : Kalo dijumlahkan hasilnya 90 derajat - saya gatau corresponding, maaaaf - sudut dalam bersebrangan Sifat : Besarnya sama - sudut luar bersebrangan Sifat : Besarnya sama - sudut bertolak belakang Sifat : Besarnya sama Maaf kalau salah
16. yg bisa bantuin yakk.. the sum of the three angles of triangle is 180degree. the sum of the angle is equal to the third angle and the difference of the two angles is equal to 2/3 the third angle. find the angles of this triangle
Misalkan sudut A,B,C
A=B
A+B=⅔C
A+B+C=180
1:1:3=180
maka
2A+3A=180
5A=180
A=180/5
A=36
A+B+C=180
36+36+C=180
C=180-72
C=108
Jadi sudut A=36, B=36 dan C=108
