Answer:
x = 55.6
Step-by-step explanation:
Recall the 3 main trig functions
Sin = opposite / hypotenuse
Cos = adjacent / hypotenuse
Tan = opposite / adjacent
Note that hypotenuse = longest side length
We want to find angle "x".
We are given its opposite side length ( 19 ) as well as the adjacent side length
When dealing with the opposite and adjacent we use tan
Tan = Opp / Adj
Opp = 19 and Adj = 13
Tan(x) = 19/13
* take the inverse tan of both sides *
x = 55.6
Answer:
-2x + 7x + 34 = -2 ( 1 - 7 x ) x=4
Well, let's say the number is "x", so "x" is the 100%.
now, what the dickens is 23% of 45 anyway?
if we take 45 to be the 100%, what is its 23%?

ok, well, we know then that 4.5% of "x" is 10.35, we also know that "x" is the 100%, what is "x" anyway?
You almost had it instead of positive 35 it should be negative 35
so the answer should be -35a5b5c5
Answer:
d = 4
Step-by-step explanation:
4(3d + 23) = 12 + 32d ← distribute parenthesis on left side
12d + 92 = 12 + 32d ( subtract 32d from both sides )
- 20d + 92 = 12 ( subtract 92 from both sides )
- 20d = - 80 ( divide both sides by - 20 )
d = 4
