Sebuah sudut dengan pelurusnya mempunyai perbandingan 3:4 berapakah besar sudut tersebut?

bantuin ya kk kumohon ​

Jawab:

### 77,143°

(pendekatan 3 angka desimal di belakang koma)

Penjelasan dengan langkah-langkah:

Diketahui:

Sebuah sudut dengan pelurusnya mempunyai perbandingan 3 : 4.

Ditanya:

Besar sudut tersebut

Jawab/Penyelesaian:

Dua buah sudut saling berpelurus jika jumlah besar sudut-sudut tersebut sama dengan 180°.

Oleh karena itu, jika besar sudut tersebut dinyatakan dengan x, maka:

x = (nilai rasio x) / (jumlah rasio) × 180°

⇔ x = 3 / (3+4) × 180°

= 3/7 x 180°

= (540/7) derajat

= (77 ¹/₇) derajat

≈ 77,143°
