Cos θ - sin θ = √2 sin θ, then prove that cos θ + sin θ = √2 cos θ.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

$450 i think. hope this ☺
