Isolate cos (t): cos(t)=1/3. Use a calculator from here because the answer is not an integer or a simple number.
y = 2 (Divide each side of the equation by -45)
b = 14
Set up the equation and solve: x + 5 = -13 (next subtract 5 from each side of the equation to solve for x) x = -18
x=2 because 9-(14)=-5
Better formatting is cos(2x+20)=-0.5
It is not an equation if it does not have an equals sign. You could simplify it but not solve it.
a equals 5
yes
I think it is 3.14 that equals to pi when u solve it
You cannot solve it since it is not a true equation.
Divide each side of the equation by 10 .
Solve the following equation for A : 2A/3 = 8 + 4A
