Question

simplify cos45+sin30

Answer 1

Answer:

Step-by-step explanation:putting values of the cos 45 and sin 30 in the equation

Cos45=1/root2

Sin30=1/2

Now,putting values of sin and cos in the eqn

1/root2+1/2

2+root2/2root2

Now rationalising the term with the denominator we get

4root2 + 8/8

Taking 4 common

We get root 2 +2/2
