Answer 1

Jawab:

maaf kalo bener

Penjelasan dengan langkah-langkah:

1. 45° = 50 grade = 0.7854 radian (pembulatan ke empat desimal)

Konversi:

   1 derajat = 1/360 putaran penuh = 0.1 grade = π/180 radian

   1 grade = 9/10 derajat = 1/400 putaran penuh = π/200 radian

Maka,

45° = 45 x π/180 radian = 0.25π radian

45° = 45 x 4/9 grade = 50 grade

2. 600 grade = 10.472 radian (pembulatan ke tiga desimal)

Konversi:

   1 derajat = 1/360 putaran penuh = 0.1 grade = π/180 radian

   1 grade = 9/10 derajat = 1/400 putaran penuh = π/200 radian

Maka,

600 grade = 600 x π/200 radian = 3π radian

600 grade = 600 x 9/10 derajat = 540 derajat

3. 3/4π rad = 135° = 150 grade (pembulatan ke bilangan bulat terdekat)

Konversi:

   1 derajat = 1/360 putaran penuh = 0.1 grade = π/180 radian

   1 grade = 9/10 derajat = 1/400 putaran penuh = π/200 radian

Maka,

3/4π rad = 3/4 x 180/π derajat = 135 derajat

3/4π rad = 3/4 x 200/π grade = 150 grade
