Answer: 55.4
Step-by-step explanation:
Remember soh cah toa
tangent = adjacent/opposite
angle is 18 degrees
Opposite is 18
Adjacent is x
So tangent of 18 degrees = 18/x
Use calculator to find tangent of 18 =0.3249
So 0.3249 = 18/x
Reciprocal both sides
3.0777 = x/18
Multiply both sides by 18
x = 55.3983
You may need to round

Hi,
Sorry, I don't use the ladder method, but I can show you how to find the <span>least common multiple of 2 numbers using a different method:
Let's say we are finding the least common multiple of 3 and 9:
3: 3, 6, 9, 12, 15, 18
--
-------------------------------
9: 9, 18, 27, 36, 45, 54
--
All I did was list multiples of both the numbers till I found one that was common (however, in the example above, I listed a few extra)
Hope this helped
:)

Answer:
x = 18.
Step-by-step explanation:
As they are congruent, BC = DC so
x + 12 = 2x - 6
12 + 6 = 2x - x
x = 18.
