Question

Solve for x. Round your answer to 2 decimal places.

Answer 1

notice your triangle
you have the "adjacent" side, 18
and the angle, the hypotenuse is "x", so

and solve for the hypotenuse

Answer 2

cos(50) = 18/x

Answer 3

11.6?

Answer 4

\(\bf cos(\theta)=\cfrac{adjacent}{hypotenuse}\implies hypotenuse=\cfrac{adjacent}{cos(\theta)}\)

Answer 5

28.00?
