5. Solve the equation |4 − 2x| = 10, giving you answer correct to 3 significant figures
the solution of |f(x)| = c, (with c is constant) is :
setting up f(x) = c or f(x)= -c
so,
if given |4 - 2x| = 10, then
4 - 2x = 10
-2x = 6
x = -3
or
4 - 2x = -10
-2x = -14
x = 7
solution = {-3, 7}

Penjelasan dengan langkah-langkah:
find tan² 22.5° =
tan 22,5 = tan ¹/₂(45)
[tex]\sf tan \ 22,5 = \dfrac{sin\ 45}{1 + cos \ 45}[/tex]
