Question

If Cos A=Sin B then find A+B​

Answer 1

Answer:

cosA =sinB

Step-by-step explanation:

we know that ,

cos45°= 1/√2

sin45°=1/√2

therefore ,

A+B=>45°+45°=90°

Answer 2

$\underline{\bigstar{\sf\ Given}}$

cos A = sin B

$\underline{\bigstar{\sf\ To\:find}}$

A + B

Step-by-step explanation:

We know that , value of cos and sin is equal at 45°

cos A = cos 45° = 1/√2

sin A = sin 45° = 1/√2

From here , we find that A = 45° and B = 45°

So,

A + B = 45 + 45 = 90°
