Question

If 2 cos 0 + sin 0 = 1, then 7 cos 0 + 6 sin 0
equal​

Answer 1

Answer:

6

Step-by-step explanation:

2cos0 + sin 0 = 1

2cos0 =1-sin0

cos0=(1-sin0)/2

now put the value of 0 in the eqn formed

=>0 =90 degree

7 cos90+6sin90=0+6

                           =6

because sin 90 = 1

cos 90 = 0
