Toko sepatu memberi diskon 30% untuk semua barang.Jika tasya membeli sepasang sepatu dan ia membayar Rp 336.000,00 setelah mendapat diskon,harga sepasang sepatu tersebut sebelum diskon adalah

Answers

Answer:

IDR 480,000

Step-by-step explanation:

Persentase diskon = Harga lama - Harga baru / Harga lama

Harga lama = Harga sebelum diskon = x

Harga Baru = IDR 336000

Persentase diskon = 30%

Karenanya:

30% = x - 336000 / x

30/100 = x - 336000 / x

0.3 = x - 336000 / x

Cross Multiply

0.3 × x = x - 336000

0.3x = x - 336000

x - 0.3x = 336000

0.7x = 336000

x = 336000 / 0.7

x = IDR 480,000

Step-by-step explanation:

The value of k using the law of sines is 2.05.

What is a law of sine?

Law of sines is a formula relating the length of the sides of a triangle to the angles of the triangle.

In Triangle JKL

< K J L = 58 degrees

< J L K = 38 degrees.

and, J K = 2.3,  J L = k.

As, <KJL + <JKL + <LKJ = 180

58+ 23 + <LKJ = 180

<LKJ = 99 degree.

Using Law of sines

k/ sin K = j/ sin J

k/ sin 99 = 2.3/ sin 58

k- 2.05
