Answer:
x = 10
Step-by-step explanation:
A triangle's angles add up to 180 degrees, so 180-90 (the right angle) is 90 degrees. That means that
4x+6+3x+14 = 90. Then we simplify so
7x + 20 = 90. Then we can subtract 20 from each side so
7x = 70. Then, we find that
x = 10.
There are no easy four steps in solving an equation. In fact it involves a lot of assessment and knowledge from the past and the current in order to make a solution for the problem. It is like solving a puzzle which may or may not contain what you already know. Here are a summarized four steps in solving an equation.
1) Clear out any fractions in the equation by multiplying each term by the highest common denominator to simplify the equation. Add or subtract other values to make it even more simplified.
2) If there is a common divisor in the equation, divide each term by the value to simplify it more.
3) Combine like terms by either cancelling or transposing terms. Factor out anything that can be factored (as long as it is simplified, the better)
4) Recognize a pattern and use different techniques, whether algebraic or trigonometric or other functions like squaring both sides.

Answer:
12e+7f
Step-by-step explanation:
you gather like terms
5e+7e =12e
8f-f=7f
12e + 7f
Cos(<span>θ) < 0, so we know it would be in Quadrant 2 or 3
then csc(</span>θ) = 257, but csc(θ) =
= 257
==> sin(<span>θ) =
it is positive, so now we can determine that is in Quadrant 2
sin(</span>θ) = opp./hyp both of opp and hyp are positive but adj suppose to negative because that way it leads the cos(<span>θ) < 0
</span>cos(<span>θ) = adj/hyp
</span>Pythereom to find the adj:
cosθ =
tanθ =
cos<span>θ = </span>
Answer:
"Commutative property of addition and of multiplication"
Step-by-step explanation:
This is the "commutative property" of addition and of multiplication. That as its name indicates tells us for additions, that if we add A + B, or B + A, we should get the same result. Similarly, the "commutative property" of multiplication tells us that if we perform the product A * B we should get the same answer as if we perform the product: B * A.
