Answer:

B. Angle X is the largest angle.

C. Angle Z is greater than angle Y.

E. Line segment X Z is the shortest side.

Step-by-step explanation:

YZ = 2n, XZ = n - 2, XY = n + 4 and n ≥ 5.

YZ - XZ = 2n - (n - 2) = n + 2. but n ≥ 5, hence YZ - XZ = n + 2 ≥ 7.

YZ > XZ

YZ - XY = 2n - (n + 4) = n - 4. but n ≥ 5, hence YZ - XY = n - 4 ≥ 1

YZ > XY

XY - XZ = n + 4 - (n - 2) = 6: XY > XZ

Therefore:

YZ > XY > XZ

The angles are proportional to their opposite sides, hence:

∠X > ∠Z > ∠Y

A. Line segment XY is the longest side.

This is wrong because YZ is the longest side.

B. Angle X is the largest angle.

This is correct. ∠X is the largest angle because it is opposite to the longest side (YZ)

C. Angle Z is greater than angle Y.

This is correct. ∠Z is opposite to the side XY while ∠Y is opposite to the side XZ

D. Line segment XZ is opposite the largest angle.

This is wrong. ∠X is the largest angle which is opposite to the longest side (YZ)

E. Line segment X Z is the shortest side.

This is correct

Solve: 5x(8-4) divide 4-2=
nataly862011 [7]

5x(8 - 4)/4 - 2

Remember to follow PEMDAS.

First, subtract 8 and 4

8 - 4 = 4

5x(4)/4 - 2

Next, follow the left -> right rule, and multiply 5x and 4

5x(4) = 20x

Divide by 4

20x/4 = 5x

Finally, note that one has a variable, and the other has a constant, and so you cannot combine.

5x - 2 is your answer

hope this helps

  What values for θ (0 ≤ θ ≤ 2pie ) satisfy the equation? 
svetoff [14.1K]
Factor out the cos<span>θ:
</span>cosθ (2sin<span>θ + sqrt3) = 0
</span>Therefore, the only ways this can happen are if either cosθ = 0 or if (2sin<span>θ + sqrt3) = 0
</span>The first case, cosθ = 0 only at θ <span>= pi/2, 3pi/2.
</span>The second case, <span>(2sin<span>θ + sqrt3) = 0 simplifies to:
</span></span>sin<span>θ = (-sqrt3)/2
</span><span><span>θ = 4pi/3, 5pi/3
</span></span><span><span>Therefore the answer is A.
