Question

tolong bantu jawab yh kk, soalnya hari ini dikumpulnya ​

Answer 1

Materi : Garis dan Sudut

Soal Nomor 1

Konsep Penyiku ( 90° )

x + 28° + 6x - 15° = 90°

7x = 90° - 13°

7x = 77°

x = 11°

∠SQT = ( x + 28° ) = 39°

∠TQR = ( 6x - 15° ) = 51°

Soal Nomor 2

Konsep Penyiku ( 90° )

6x - 2 + 5x + 11 + 7x + 9 = 90°

18x + 18 = 90°

18x = 72°

x = 4°

Hasil / Result :

∠DAE = ( 6x - 2 ) = 24 - 2 = 22°

∠CAD = ( 5x + 11 ) = 20 + 11 = 31°

∠BAC = ( 7x + 9 ) = 28 + 9 = 37°

Semoga bisa membantu

Answer 2

Verified answer

1) x + 28° + 6x - 15° = 90°

(1 + 6)x + (28 - 15)° = 90°

7x + 13° = 90°

7x = (90 - 13)°

7x = 77

x = (77/7)°

x = (11/1)°

x = 11°

MAKA :

SQT

= (11 + 28)°

= 39°

TQR

= (6 × 11 - 15)°

= (66 - 15)°

= 51°

2) 6x - 2 + 5x + 11 + 7x + 9 = 90°

(6 + 5 + 7)x + (11 - 2 + 9)° = 90°

(11 + 7)x + (9 + 9)° = 90°

18x + 18° = 90°

18x = (90 - 18)°

18x = 72°

x = (72/18)°

x = 4/1

x = 4°

MAKA :

DAE :

= (6 × 4 - 2)°

= (24 - 2)°

= 22°

CAD :

= (5 × 4 + 11)°

= (20 + 11)°

= 31°

BAC :

= (7 × 4 + 9)°

= (28 + 9)°

= 37°
