Just need help with the way. thanks!

KN ≈ 20.7 cm

Step-by-step explanation:

Using Pythagoras' identity in right triangle KLM to find KM

LM² = KL² + KM²

28² = 16² + KM²

784 = 256 + KM² ( subtract 256 from both sides )

528 = KM² ( take the square root of both sides )

= KM

----------------------------------------

Using the sine ratio in right triangle KMN

sin64° = = = ( multiply both sides by

× sin64° = KN , that is

KN ≈ 20.7 cm ( to 1 dec. place )

you're missing vital information, add to it so we can solve this problem for you.

step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
