Question

What is the first step of solving
?
(1 point)
cos
(
42
)
=
18
x
divide both sides by 18
divide both sides by x
multiply both sides by 18
multiply both sides by x
B)
What is the second step?
(1 point)
divide both sides by the cos(42)
multiply both sides by cos(42)
divide both sides by x
divide both sides by 42
x is by itself, so you put the other side of the equation in your calculator

Answer 1

If the equation is cos(42) = 18x, then:

1) First step: divide both sides by 18 to isolate x → x = cos(42)/18.

2) Second step: evaluate the right side on a calculator (compute cos(42) then divide by 18).
Numerically (with 42°): x ≈ cos(42°)/18 ≈ 0.7431448/18 ≈ 0.0413.
