Answer:
cos L = 55/73
Step-by-step explanation:
The triangle KLM is a right angle triangle. The ∠M = 90°. The side KM = 48, LK = 73, and ML = 55. The ratio that represents the cosine of ∠L can be solved below.
The right angle triangle formed has an hypotenuse , opposite and an adjacent side. Using the SOHCAHTOA principle one can find the ratio that represent the cosine of ∠L.
opposite side = 48
adjacent = 55
hypotenuse = 73
cos L = adjacent/hypotenuse
cos L = 55/73

Answer:
y = 5/6x -2
Step-by-step explanation:
Subtract 5x and divide by -6:
-6y = -5x +12 . . . .subtract 5x
y = 5/6x -2 . . . . . divide by -6
Use cosine law to solve the problem. See image attached.
What we're looking for is the length of side A (a side which is opposite with angle A).
This is the formula of cosine law
A² = B² + C² - 2BC cos A
Input the numbers
A² = 75² + 90² - 2(75)(90) cos 85°
A =
A =
