Answer:
N(-2) = -5 this is also equal to n=2.5
Step-by-step explanation:
multiply both sides by 2
-4n = -2n-5
add 2n to both sides
-2n = -5
divide both sides by -2
n=2.5

Answer:
x = 2
Step-by-step explanation:
The parallel lines divide the transversals into proportional segments, that is
=
( cross- multiply )
9(x + 4) = 54 ( divide both sides by 9 )
x + 4 = 6 ( subtract 4 from both sides )
x = 2
To solve for the longest side, the hypotenuse, you have to use the pythagorean theorem. It will be 10^2 + 9^2 = c^2. 100 + 81 =c^2.
c^2 = 181 so c = sqrt(181).
to find sin of A do opposite/hypotenuse which gives you 9/sqrt(181)
to find cos of A do adjacent/hypotenuse which gives you 10/sqrt(181)
c^2 = 181 so c = sqrt(181).
to find sin of A do opposite/hypotenuse which gives you 9/sqrt(181)
to find cos of A do adjacent/hypotenuse which gives you 10/sqrt(181)
