We have to calculate the length of stack RM. This is a pyramid with a rectangular base. If TS = 12 cm, then OM = TS / 2 = 12 / 2 = 6 cm. And since we already know that RO = 15 cm, we will use the Pythagorean theorem: RM^2 = 15^2 + 6^2; RM^2 = 225 + 36 = 261; RM = sqrt ( 261 ) ; RM = 16.1555 ( or 16.2 rounded to the nearest tenth ). Answer: RM = 16.2 cm<span>.</span>

The students in a furniture making class make a tabletop shaped like the figure shown.
Rama09 [41]

Answer:

The area of the given figure is equal to the area of a rectangle with sides 5 feets by 6 feets less the area of four square cut-outs of side 1 feet.

Area of the rectangle = 5 x 6 = 30 square feets.

Area of the four square cut-outs = 4(1 x 1) = 4 x 1 = 4 square feet

Area of the given figure = 30 - 4 = 26 square feet.

Area of a triangle = 1/2 x base x height

i.e. 1/2 bh = 26

bh = 26 x 2 = 52

possible values of base and height = (1 and 52), (2 and 26), (4 and 13)

Step-by-step explanation:

Hope this helped.

A brainliest is always appreciated.

Consider the given parallelogram KLMN.

Prove: \angle N \cong \angle L, \angle K \cong \angle M

 Statement                                                                       Reason

1. KL \parallel NM, KN \parallel LM               Definition of parallelogram

2. \angle K+ \angle N = 180^\circ                 Same Side interior angle theorem

   \angle L+ \angle M = 180^\circ

  \angle K+ \angle L = 180^\circ

3. \angle K+ \angle N=\angle K+ \angle L   Substitution property

  \angle L+ \angle M=\angle K+ \angle L

4. \angle N = \angle L                                 Subtraction property of equality

  \angle M = \angle K

Subtraction property of equality tells us that if we subtract some number from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same.

5.  \angle N \cong \angle L                         Angle Congruence Postulate

  \angle M \cong \angle K

When two angles are equal, then they are said to be congruent by Angle congruence postulate.
