Question

if cos 0 ° + root 2 sin 45° + sin A = 3 , then value of A =​

Answer 1

Step-by-step explanation:

by solving the value of A=90⁰

Answer 2

Step-by-step explanation:

cos 0 ° + root 2 sin 45° + sin A = 3

=>1+[√2×(1/√2)]+sinA=3

=>1+1+sin A=3

=>2+sin A=3

=>sin A=3-2

=>sin A=1

=>sin A=sin 90°

therefore,A=90°
