PLZ HELP! Need this ASAP! Thx so much!<br><br> Find m∠PMK<br><br> Plz show ur work!

In ∆MKP and ∆MNP

MK = MN

PK = NP

MP = MP

SO ∆MKP AND ∆MNP ARE CONGRUENT.

SO m<PMN = m<PMK


m<NMK = 50

=> m<PMN + m<PMK = 50

=> 2 m<PMK = 50

=> m<PMK = 50/2 = 25°

Given parallelogram SNOW, diagonals SO and NW intersect at D.
Reil [10]

Answer:

The length of SO is 46 units

Step-by-step explanation:

<em>In a parallelogram, </em><em>diagonals bisect each other,</em><em> which means meet each other in their mid-point</em>

∵ SNOW is a parallelogram

∵ SO and NW are diagonals

∵ SO ∩ NW at point D

→ That means D is the mid-point of SO and NW

∴ D is the mid-point of SO and NW

∵ D is the mid-point of SO

→ That means D divide SO into two equal parts SD and DO

∴ SD = DO

∵ SD = 9x + 5

∵ DO = 13x - 3

→ Equate them

∴ 13x - 3 = 9x + 5

→ Subtract 9x from both sides

∵ 13x - 9x - 3 = 9x - 9x + 5

∴ 4x - 3 = 5

→ Add 3 to both sides

∵ 4x - 3 + 3 = 5 + 3

∴ 4x = 8

→ Divide both sides by 4

∴ x = 2

→ To find the length of SO substitute the value os x in SD and DO

∵ SO = SD + DO

∵ SD = 9(2) + 5 = 18 + 5 = 23

∵ DO = 13(2) - 3 = 26 - 3 = 23

∴ SO = 23 + 23 = 46

∴ The length of SO is 46 units

If a cube has a side length of 4 1/2 cm, what is one way to write the volume of the cube?
atroni [7]

For this case we have that by definition, the volume of a cube is given by: V = s ^ 3

Where,

  • <em>s: Side of the cube </em>

We have that the cube side is given by:

s = 4 \frac {1} {2} cm

Therefore, replacing values we have:

V = (4 \frac {1} {2}) ^ 3 cm ^ 3

Answer:

One way to write the volume of the cube is:

V = (4 \frac {1} {2}) ^ 3 cm ^ 3
