What is the length of segment lm? units

The answer is: The length of segment LM is 23 units.

Step-by-step explanation:

From the figure, we know that:

KL ≅ LM

9x + 5 = LM

KN ≅ NM

14x - 3 =25

With that alone we can solve for what x is:

             Add 3 to both sides of the equation to eliminate -3

Divide both sides by 14 to eliminate 14

Now that we have x, we just plug that in our equation of KL to solve for LM:

answer: c

(2, -4)

goes 7 to the

(9, 4)

easy

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
