Question

if Sin alpha = 1/2 cos bita = 1/2 find alpha + bita​

Answer 1

Answer:

Hey mate! Here's your answer:

Step-by-step explanation:

Sin 30° = 1/2, so Alpha = 30°.

Cos 60° = 1/2, so Beta = 60°.

Alpha + Beta = 30° + 60° = 90°.

Answer 2

Step-by-step explanation:

sinα= 1/2

Hence α=30

Similarly,

cosβ= 1/2

Hence β=60

Therefore

α+β=60 +30

=90
