Answer 1

Panjang sisi miring² = 1² + 3²

paniang sisi miring = √10

Cos A = samping / miring

Cos A = 3/√10

Cos A = 3/10 √10 (B)

Answer 2

cari sisi miring:

m = √(3² + 1²)

m = √(9 + 1)

m = √10

sin A = sisi depan/ sisi miring

sin A = 1/√10

sin A = 1/10√10

cos A = sisi samping/ sisi miring

cos A = 3/√10

cos A = (3 × √10)/(√10 × √10)

cos A = 3√10/10

cos A = 3/10 √10

• opsi B
