Answer:
WY = 30
XZ = 10.5
Step-by-step explanation:
Paralellogram's diagonal's bisect eachother
Therefore,
Move the n over,
2n = 7
Divide both sides by 2,
n = 3.5
WY = 2(ZY) because definition of bisector
Simplify...
WY = 2(4n+1)
WY = 2(4(3.5)+1)
WY = 2(15)
WY = 30
You asked for XY, but the question asks for XZ, so I'm going to give XZ.
With n = 3.5 from above,
XZ = 3n
XZ = 3(3.5)
XZ = 10.5

Answer:
Step-by-step Explanation:
Given:
∆RST,
m < T = 17°
t = RS = 5
m < S = 20°
s = RT = ?
Apply the Law of Sines to find s
Multiply both sides by sin(20) to make s the subject of formula.

Answer:
x = −2 or x = 4.23606797749979 or x = −0.2360679774997898
Step-by-step explanation:
Subtract x^3-2x^2-9x-2 from both sides.
0 − (x3−2x2−9x−2) = x3−2x2−9x−2 − (x3−2x2−9x−2)
−x3+2x2+9x+2=0
Factor left side of equation.
(−x−2)(x2−4x−1)=0
Set factors equal to 0.
−x−2=0 or x2−4x−1=0
