Answer 2

Answer:

Step-by-step explanation:

Value of (sina)+(cosa) depends on the value of angle a,

•If a=0 degree

Sina + Cosa = 0+1=1

•If a = 30 degree

Sina + Cosa = 1/2+√3/2=(√2+2√3)/2√2

•If a = 45 degree

Sina + Cosa = 1/√2+1/√2=2/√2=√2=1.414

=>As the value of angle a inscreses the value of (Sina +Cosa) increases....
