Prove that if a parallelogram is a rhombus then each diagonal bisects a pair of opposite angles. complete the proof. since jklm is a rhombus jm~= lm and jk~=lk. mk~=mk by the reflective property of congruence. so, mjk~=mlk by the (asa, sas, sss) triangle congruence theorem. therefore, jmk~= (mln, mnl, lmk) and jkm~=(lkn, lkm, lnk) by cpctc so mk bisects jml and jkl. is similar argument shows that jl bisects mjk and mlk

answer:

your answer is: c. 196 7/8 in^3.

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
