Write the product cos(2x)sin(5x) as a sum

Step-by-step explanation:

Given:

Formula:

Compare the given expression with formula

Therefore,

Using two system of equation of A and B to solve for A and B

Add both equation to eliminate B

Substitute A into A+B=10x

Substitute A and B into formula

Hence, Product as sum form

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
