Question

sin is equal to 1 by 2 and cos b is equal to 1 by 2 find the value of a + b​

Answer 1

Answer:

A+B = 90°

Explanation:

Given

i ) sinA = \frac{1}{2}

\implies SinA = sin30

Now ,

A = 30° ----(1)

ii ) cosB = \frac{1}{2}

\implies cosB = Cos60

=> B = 60° ----(2)

Now,

Value of (A+B)

= 30°+60° [ from (1)&(2) ]

= 90°

Therefore,.

A+B = 90°

Answer 2

Answer:

Hi

your answer is

Given

sin a = 1/2

cos b= 1/2

sina = sin 30° , a=30°

cosb. =cos 60°. b= 60°

$o a+b = 90
