Question

Ifa cos 0 + b sin 0 = 3 and asino - bcos 0 = 4,
then a2 + b2 = ?​

Answer 1

Answer:

d) non of these.

Step-by-step explanation:

since cos 0 is 0 and sin0 is subtitued in epuation cos0+sin0=3.we get.

thhen,a(0)+b(1)=3

b=3.

and

a) sin 0-6 cos 0=4.

a=4

so here 'a' value is 4 and 'b' value of 3.

2(4)+2(3)

8+6

14

non of these
