Angle Z is congruent to angle C, so angle C measures 4x+8
the sum of the three angles of a triangle is 180, so 
50+2x+40+4x+8=180
6x++98=180
6x=82
x≈13.67

Solve the poprotion 38/25=n/12
ANEK [815]

Answer:

  n = 18 6/25

Step-by-step explanation:

Multiply both sides by 12.

  12(38/25) = 12(n/12)

  456/25 = n = 18 6/25 = 18.24

Pls help me with this question ​
Andrei [34K]

Answer:

0

Step-by-step explanation:

(sin(2n) − 1) / (sin n − cos n)

-(1 − sin(2n)) / (sin n − cos n)

-(1 − 2 sin n cos n) / (sin n − cos n)

-(sin² n − 2 sin n cos n + cos² n) / (sin n − cos n)

-(sin n − cos n)² / (sin n − cos n)

-(sin n − cos n)

cos n − sin n

Limit as n approaches π/4 is 0.

If the diagonals of a quadrilateral bisect the angles, is the quadrilateral always a parallelogram? Explain your answer.
Liula [17]
Yes. If the diagonals bisect the angles, the quadrilateral is always a parallelogram, specifically, a rhombus.


Consider quadrilateral ABCD. If diagonal AC bisects angles A and C, then ΔACB is congruent to ΔACD (ASA). Hence AB=AD and BC=CD (CPCTC).

Likewise, if diagonal BD bisects angles B and D, triangles BDA and BDC are congruent, thus AB=BC and AD=CD. (CPCTC again). Now, we have AB=BC=CD=AD, so the figure is a rhombus, hence a parallelogram.
